Subtropical Storm Beryl forms

The second named storm of this unusually fast-starting 2012 Atlantic hurricane season is here. Subtropical Storm Beryl formed Friday night, a few hundred miles east of the South Carolina coast, from an area of disturbed weather that had moved from the Western Caribbean northeastward. Beryl's formation marks the first time since the hurricane season of 1908 that two Atlantic named storms have formed so early in the year. The only other year with two storms so early in the year was 1887. Records of tropical cyclones in the Atlantic extend back to 1851.


Figure 1. Morning satellite image of Beryl.

The clockwise flow of air around an extremely intense ridge of high pressure that is bringing record heat to the Midwest this weekend is currently driving Beryl to the southwest, and this motion is likely continue until Beryl is very close to the Georgia/Northern Florida coast on Sunday night. As I explain in my Subtropical Storm Tutorial, a subtropical storm typically has a large, cloud free center of circulation, with very heavy thunderstorm activity in a band removed at least 100 miles from the center. The difference between a subtropical storm and a tropical storm is not that important as far as the winds they can generate, but tropical storms generate more rain. A key difference between tropical and subtropical storms is that tropical systems have the potential to quickly grow into hurricanes, while subtropical storms do not. Thus, we need not be concerned about Beryl intensifying to hurricane strength while it is still subtropical. If the storm manages to build a large amount of heavy thunderstorms near its center, these thunderstorms should be able to add enough heat and moisture to the atmosphere to turn Beryl into a tropical storm. This process will be aided as Beryl passes over the warmest waters of the Gulf Stream Saturday night and Sunday morning. But as Beryl makes its likely transition to a tropical storm on Sunday afternoon and evening as it approaches the coast, the storm will move off of the warmest Gulf Stream waters into waters that are cooler (25°, 77°F), and with with lower total heat content. This will limit the storm's potential to strengthen. The 11 am Saturday wind probability advisory from NHC gave Beryl just an 8% chance of becoming a hurricane. There is a lot of dry air surrounding Beryl, thanks to an upper-level low pressure system aloft, and this will keep rainfall amounts much lower that what we would expect if Beryl was a tropical storm. Thus, flooding due to heavy rains is probably not a huge concern with this storm, particularly since the Southeast U.S. coast is under moderate to extreme drought. The 2 - 4 inches of rain expected from Beryl will not be enough to bust the drought, since the Southeast U.S. is generally suffering a rainfall deficit of 8 - 12 inches (since October 1.) Heavy rains from Beryl are not likely to begin affecting coastal South Carolina, Georgia, and Northern Florida until Sunday.

Bud hits Mexico and dissipates
Hurricane Bud hit Mexico as a tropical depression early this morning, and has now dissipated, thanks to dry air, wind shear, and interaction with Mexico's mountainous terrain. As Bud approached Mexico on Friday, it brought tropical storm-force winds and heavy rains to the coast. Winds at Manzanillo peaked at 41 mph, with a gust to 55 mph, Friday afternoon. Thursday night at 11 pm EDT, Bud peaked at Category 3 status, with 115 mph winds, becoming the earliest Category 3 hurricane on record so early in the year in the Eastern Pacific. There are no reports of deaths or damage from Bud so far, and with only another inch or so of rain expected from the storm, Mexico appears to have escaped serious damage.

Post 1217 great another infamous yet familiar name to add to my ignore list.

Anyway...definitely looking like Beryl is attaining tropical characteristics. I wouldn't be surprised to see Tropical Storm Beryl when I wake up tomorrow morning. (and a stronger storm I might add)

Look at all the different little perturbations on the 72-hr TAFB map... fascinating.

I'm starting to think there's more of a correlation between instability and active seasons than I previously understood.

That coastline does get up to Cat 2 storms from time to time. I mean making landfall from the ATL side, btw. I think the JAX area gets impacted more frequently by storms exiting FL on recurve.

I don't think the winds would do that much damage, but I could see, at least potentially, water-related problems if the buildings are close to the shore or in lowlying areas.


Didnt Fay make landfall near JAX as a hurricane?

yea because they just adjusted it southward

I looked at the forecast track archive and the position from this afternoon to 11pm was south of where they said it would be

The last hurricane to make a direct landfall in Jacksonville was Dora in 1964. Other than that, you are right, Jacksonville usually gets the exiting storm from the GOM side.

Tonight's diurnal max and how Beryl interacts with the Gulf Stream will determine the rest of it's short life. 

Could strengthen 10-15 knots (as the HRW and 4km NAM suggest), or just fluctuate tomorrow.

Looks like the Gulf of Mexico is the main area of concern this year...

The reason why you don't remember anything, is that nothing has come close in 50+ years.

Good point Brickell - I wonder how much they are built to withstand seeing how old some of them are.


If they have survived over 400 years, I'm sure they can survive a few hours of 50mph wind.

hey guys longtime lurker here. I post occasionally but this time is very relevant. any input on possible impact to Mims/Titusville area? It looks like Beryl hasn't turned ans se4ems to be heading my way.

The official track is close to St. Augustine, so Mims shouldn't have too many problems. That's subject to change, though, so keep an eye on the storm and listen to your local officials.

I gave up this morning Bro, lol. Just turned 36 on Wednesday, surely not wasting any unnecessary brain cells on this one, there will be many more for sure.


Hell, you're a young buck...I'm about to hit 40 in a couple month. And yet I'm still throwing brain cells down the tropical tracking conundrum.

I concur Baha, areas N of landfall will see the most from this system.


As for drought buster, it has a long way to go before becoming a true soaker imho.

Nope, not particularly. I guess maybe sort of once it starts it's track N. But models will come out at that time, and want to see what the sat looks like then. See if it manages to start getting any yellows and oranges in that image I just posted.

Night time is when everything happens ;) And I've always been a part of the late night crew...


Alright, Beryl has the potential to be a drought buster from Central Florida to Virginia.

I'd say the further south it gets, the more your chances of impacts. However, unless it makes landfall south of St. Augustine, you will likely not get the worst of it. I'm thinking points north of the centre would prolly get more intense weather.
