Tropical Storm Beta made landfall near Port O’Connor, Texas at 11 p.m. EDT Monday, September 21, 2020, with sustained winds of 45 mph and a central pressure of 999 mb. Beta is the ninth named storm to make a U.S. landfall in 2020, tying a record held by 1916 for most U.S. landfalls by Atlantic storms in a season.
At 11 a.m. EDT Tuesday, Beta, by then weakened to a tropical depression with 35 mph winds, was located inland along the middle Texas coast. Crawling to the northeast at 2 mph, Beta is expected to continue moving at less than 5 mph, roughly parallel to the coast, through Wednesday, allowing the storm to spread heavy rains over Texas and Louisiana for multiple days. Most models predict Beta’s center will not emerge back over water, or will move offshore the Texas coast for just a few hours, so the storm is likely to gradually spin down and dissipate by Friday, given that wind shear is expected to remain high throughout the week. But with a portion of its circulation remaining over water, Beta will be a copious rainmaker.
Heavy rains from Beta were affecting much of the Texas and Louisiana coasts on Tuesday. Rains of 4 – 8 inches had already fallen over coastal Louisiana near the mouth of the Mississippi River, and rainfall amounts along the Texas coast were generally 3 – 5 inches, with one area southeast of Houston seeing over a foot of rain (Figure 1).
The live storm surge tracker at Trabus Technologies showed Beta continued to bring storm surge heights of two to three feet along much of the Texas and Louisiana coasts.
Here are some observed storm surge heights at 11 a.m. EDT Tuesday:
– 3.4 feet: Rollover Pass, Texas (east of Houston);
– 3.1 feet: Matagorda Bay, Texas (southwest of Houston);
– 3.0 feet: Shell Beach, Louisiana (east-southeast of New Orleans); and
– 2.5 feet: San Luis Pass, Texas (south of Houston).
Beta is record-tying ninth named storm in one season to hit U.S.
Beta is the ninth named storm to make landfall in the U.S. so far in 2020, setting a record for the earliest a ninth named storm has made a U.S. landfall. Only one other hurricane season has had as many as nine U.S. landfalls during a full season: 1916. Second place is held jointly by 2005, 2004, and 1985, with eight. Here are the other Atlantic named storms in 2020 to hit the U.S., along with their preliminary damage estimates from insurance broker Aon (except for the Sally damage estimate, which is from hurricane damage expert Chuck Watson):
- Hurricane Sally near the Alabama/Florida border on September 9 (105 mph winds, 7 deaths, $8+ billion in damage);
- Hurricane Laura in southwest Louisiana on August 27 (150 mph winds, 33 deaths, $10+ billion in damage);
- Tropical Storm Marco in southeast Louisiana on August 24 (40 mph winds, over $2 million in damage to the U.S., and over $20 million in Mexico and Costa Rica);
- Hurricane Isaias near Wilmington, North Carolina, on August 3 (85 mph winds, over $5 billion in damage to the continental U.S.);
- Hurricane Hanna in South Texas on July 25 (90 mph winds, $775 million in damage to the U.S. and $100 million to Mexico);
- Tropical Storm Fay in New Jersey on July 10 (50 mph winds, six deaths, $350 million in damage);
- Tropical Storm Cristobal in Louisiana on June 7 (50 mph winds, one death, $325 million in damage); and
- Tropical Storm Bertha in South Carolina on May 27 (50 mph winds, $200 million in damage).
Between 1851 and 2019, the U.S. averaged 3.2 named storm landfalls per year, 1.6 hurricane landfalls, and 0.5 major hurricane landfalls.
Beta is the first U.S. landfalling “Greek” named storm. The only other year with “Greek” named storms, 2005, had three that made landfall – Alpha, Beta, and Gamma – all in the Caribbean.
Category 2 Teddy headed for Nova Scotia and Newfoundland
Hurricane Teddy is on the home stretch of its trek towards Nova Scotia and Newfoundland, Canada, with landfall expected to occur Wednesday morning. At 11 a.m. EDT Tuesday, Teddy had strengthened to a category 2 storm with top sustained winds of 105 mph and a central pressure of 950 mb. Teddy was headed north-northwest at 16 mph as a gigantic hurricane, with tropical storm-force winds extending out as much as 415 miles from the center, and hurricane-force winds extending out up to 140 miles from the center.
Teddy’s enormous wind field had created waves 12 feet high spanning an area of ocean over 1,800 miles across, with a 100-mile-wide area of waves over 50 feet high near the center. The hurricane was generating big swells and dangerous surf conditions and riptides along much of the U.S. East Coast and the Maritime Provinces of Canada, with waves of 10 – 15 feet common in the offshore waters.
Forecast for Teddy
Teddy absorbed energy from the trough of low pressure steering it to the north, allowing it to intensify to a category 2 hurricane. However, the hurricane has now wrung out as much energy as it could from that interaction, and it now is in the process of transitioning to a powerful extratropical storm.
Teddy’s wind field has peaked in size, and the hurricane is expected to steadily weaken as it approaches landfall, given cooler waters and high wind shear. Landfall in Nova Scotia likely will be as a strong extratropical storm with winds of 65 – 75 mph, with heavy rain, storm surge, and widespread gale-force winds all likely to be threats.
Canadian hurricane history
Last year, ex-Hurricane Dorian rampaged through eastern Canada after making landfall in eastern Nova Scotia as an extratropical cyclone with category 2 winds of 100 mph and a pressure of 958 mb. At landfall, ex-Dorian’s wind field was huge, with hurricane-force winds that extended out 115 miles from the center and tropical storm-force winds that extended out 310 miles.
The storm’s powerful winds and storm surge caused extensive damage in Nova Scotia, and knocked out power to 412,000 customers – about 80% of the province. A buoy moored off the coast of Newfoundland measured a maximum wave height of 100.7 feet (30.7 meters) during the storm. Ex-Dorian caused $200 million in damage in Canada.
According to the NOAA Historical Hurricane Tracks website, only four category 2 or stronger hurricanes have made landfall in Canada since records began in 1851. Dorian is the only ex-hurricane that hit Canada with category 2-strength winds.
Here are Canada’s four category 2 hurricanes of record:
– Hurricane Ginny of 1963, which made landfall in southwestern Nova Scotia as a category 2 storm with 105 mph winds;
– Hurricane Gerda of 1969, which crossed into New Brunswick with 105 mph winds after making landfall in eastern Maine;
– Hurricane Michael of 2000, which made landfall in Newfoundland as a category 2 storm with 100 mph winds; and
– Hurricane Juan of 2003, which took a worst-case track and hit Halifax, Nova Scotia, as a category 2 hurricane with 100 mph winds, killing eight and causing $200 million in damage – Canada’s most expensive hurricane on record.
Paulette is back
After roaming the Atlantic for 10 days, September 7 – 16, during which time it made a direct hit on Bermuda on September 14 as a category 1 hurricane, Hurricane Paulette transitioned to a strong extratropical storm in the waters near the Azores Islands in the northeast Atlantic.
The circulation of the ex-hurricane persisted for the next five days, and ex-Paulette gradually worked its way to the south over warmer waters. On Monday night, enough heavy thunderstorms had developed near the storm’s center for Paulette to be re-designated Tropical Storm Paulette. Dr. Phil Klotzbach of Colorado State University says Paulette is the first ex-hurricane in the Atlantic since Ivan in 2004 to redevelop as a tropical or subtropical storm.
Paulette’s second incarnation will be much shorter than its first, as the storm’s eastward motion is taking it into an area with cooler waters and high wind shear that will likely make the storm post-tropical by Wednesday, and possibly sooner. The reborn Paulette will not be a threat to any land areas.
A relatively quiet period coming to the Atlantic
None of the top three models for forecasting tropical cyclone genesis are predicting formation of any new Atlantic tropical cyclones over the coming five days. As IBM meteorologist Michael Ventrice tweeted on Sunday, the Atlantic this week is experiencing passage of an atmospheric disturbance called a convectively suppressed Kelvin wave, which creates dry, sinking air unfavorable for tropical storm formation.
Consider that respite a break after seeing 10 named storms form this month – an all-time record for the month of September.
The next name on the Atlantic list of storms is Gamma. Let’s hope we don’t see it until October.

hmm not as strong!
As a long-time follower of Dr. Jeff, I am thrilled that he…and Bob Henson..landed up with Yaleclimateconnections to promulgate “Eye of The Storm” as Category 6 2.0 and then some. As I have shared with Dr. Jeff in the past, I used to fly the P-2s in the Naval Air Reserve.Our mission was NOT to fly into tropical disturbances…Jeff’s Hurricane Hunter mission was to fly into them. And one day the disturbance morphed into Hurricane Hugo. Thank God Jeff is still with us. Thank God I and I am sure many thousands of others are so very blessed to have his wisdom, insights and dynamic words/graphics to help us navigate one of the most complex hurricane seasons in perhaps 100 years.

Mitch was a bitch in an earlier October.
🙁
how do you know its Terry? Im not.

The GFS has been consistent with a low pressure system developing in the western Caribbean by October 7th.
yes im watching it closely for sure..this is the time of year when they get into the gulf then get blown into Florida by fronts..by the way..a Front will be coming down Florida 1rst week of OCT,..we’ll have to wait and see.
Right.. it has it really close to Belize and the water is extremely warm.
Yes, and it a disturbance develops, some of the better models have it heading north and then northeast. I think it is too soon to say how far north it would go before it is turned the the NEE/NE. What do you think?
It is way too soon to tell right now. As we get closer we should get better model support. We just need to keep monitoring it.
Copy that.
yes we need to wait this out and lets see what is going on say… Oct 1st
where is a low pressure system when u need it, getting sick of this hazy smoke
My latest birdseye view chart and discussion of the Atlantic tropics at this link. Even though Beta and Teddy are remnant systems, I discuss what’s going on with them and their impacts. However we are finally in for a quiet period in the Atlantic after ex-Beta and ex-Teddy diminish, with no other disturbances that are developing.

It might be a long way out , but I feel that could be more accurate than we think!
W_____A
yeah might be a dangerous one if…
Good news!
Seeing this computer forecast 12 days out is a sure thing that it wont happen.
gfs continues to have a hurricane into FLA around the 6th of OCT..long way off but it did the same long range for Sally huh..best we in FLA stay alert when oct begins..just in case huh
better to be prepared ! yes just in case!
What part of FL do you see it hitting on the West coast?

“Dr. Phil Klotzbach of Colorado State University says Paulette is the first ex-hurricane in the Atlantic since Ivan in 2004 to redevelop as a tropical or subtropical storm.”
He actually talks only about redevelopment as fully tropical storm. But even that is false. Nadine of 2012 did that. If subtropical redevelopment is included, then another case is Beryl of 2018.
Also Humberto of 2013 became TS again
Thank you Dr Masters for your updates and interesting comments on the ongoing records of the 2020 season.
A sort of 20/20 vision of what may be to come next and into the future.
Here in Spain Hurricane Paulette transitioned to a strong extratropical storm and they are very excited!
Due to the virus thing and other factors involving no tourists here, plus ambient background cooking programs, a hurricane, even if it is a long way away and failing rapidly, is to say the least a distraction.
I am monitoring the situation and as Paulette follows so close on the heels of Alpha, its all action on the weather front here, also we do not have much more to talk about. A few thunder storms and a bit of flooding in the Barcelona areas.
We are having a busy year with Alpha and Paulette, plus the Medicane. I imagine if a quiet year was in the Atlantic and if we were the only people to be getting the action, what would the comments look like? Its busy over in the Americas and you have plenty on your plates fro the next couple of months.
“Only one other hurricane season has had as many as nine U.S. landfalls during a full season: 1916. Second place is held jointly by 2005, 2004, and 1985, with eight.”
I can’t help but think it odd that 1916’s Tropical Storm #15, which hit Honduras with 70 mph winds before transitioning to extratropical and striking Key West and South Florida with 60 mph winds, is not considered a US landfall.
https://upload.wikimedia.org/wikipedia/commons/b/bf/1916_Atlantic_tropical_storm_15_track.png
On the other hand, 2005 Hurricane Ophelia did not make an official US landfall, though the eyewall was onshore and caused considerable damage. The NHC used to call these “strikes”, but now they’re calling some strikes landfalls.
I assume the NHC is trying to make things easier to understand, but sometimes I wonder.
Anyway, in my book, 2020 will have to produce 2 more US landfalls to beat out 1916.
And 2005 should just sit down for once. Such a greedy year.
Oh, you’re micatnight. Good to know 🙂
Per the NHC: “Landfall: The intersection of the surface center of a tropical cyclone with a coastline. Because the strongest winds in a tropical cyclone are not located precisely at the center, it is possible for a cyclone’s strongest winds to be experienced over land even if landfall does not occur. Similarly, it is possible for a tropical cyclone to make landfall and have its strongest winds remain over the water. Compare direct hit, indirect hit, and strike.” https://www.nhc.noaa.gov/aboutgloss.shtml
I guess NHC is pretty strict with their definitions. So 1916’s TS15 wouldn’t count because it had already transitioned to extratropical by the time it hit Florida and therefore doesn’t count as a tropical cyclone in the definition. And Ophelia doesn’t count because the actual center stayed off shore even though the eyewall made it on land – the eye was apparently 115 miles wide at that time.
The 1916 hurricane season was smack dab in the middle of the negative phase of the AMO. Highly Anomalous. It was an incredibly active season sandwiched in between quiet seasons. Of course, back then some systems were missed without question but with the exception of 1916, the years preceding and succeeding were quiescent. The new active +AMO began in approx 1928 and lasted until 1969. Negative phases tend to last around 20 years while the positive phases tend to last around 40. The new active phase started in 1995 so do the math. We should be quite active until approx 2035.
Thanks for this post Dr. Masters!
Got my latest birdseye view chart and post of the Atlantic tropics up at this link. In that post includes details of how Teddy is maintaining strength while interacting with an upper trough.
Thanks for another great post, Dr. Masters!
Thx for the updates! flash flood warnings up in Tx. crazy dayz
more to come!
The Atlantic 2020..
lol
I’m all for redesignating Paulette as another named storm, much as Grover Cleveland’s 2 terms were, 2 differently numbered. That’s Gamma!
