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.

I feel like Beryl is trying to close off an eyewall. If it had a few more days over water, I think we would see a hurricane. In any case, strengthening just before landfall is not good. This will be a HUGE rainmaker now, when yesterday it was nearly a naked swirl.

I hope yours verifies. We need the rain in central GA to relieve our D4 drought. The NHC track right now doesn't quite do us justice.

I live a mile from the ocean in jax beach, should be an interesting night. Im not getting back into town later, so hopefully the bridges will be open, it all depends if we get the north side of the storm or not as that will decide who gets the strongest winds and surge.

Wife is a member of the Jax Beach auxiliary police--she just got put on call. Damn, she won't be much fun at the Hurricane party 'cause she can't have anything to drink!

I just sent a message to the Jax Pier Cam folks telling them that they should go clean their lens on the most important day in their history.

It can't become a hurricane if it is subtropical, and your coordinates must be off because it is in the warmest waters now, and moving directly towards the cooler shelf.

If in the Impact area, time now to get those Preps done and be aware of whats coming.

Every storm is different, and this one is going to come in on the Up-tick seems.

Have a NOAA Alert Radio handy for info on the Tornadoes, and Squally weather.

Remind those who are elderly, and those who are shut in's, and help them as well.

Be Pro-active, to prevent being re-active during the storm.

Take care of one another.


Good advice, Pat. Wish that people would heed it more often. Called back to my friends and no one is really taking it very seriously. No preps, nothing. They are about an hour north of Jax and live on the river. Ugh.

On satellite, Beryl almost looks like she wants to take a bite out of the FL coast.

I am fairly pleased with my intensity forecast on Beryl I issued at 1:21 AM on May 26. As shown in Figure 2 of that post...I was predicting a peak of 65 mph winds and a tropical storm....then a weakening to 60 mph winds just before landfall (due to cool water shelf W of Gulf stream). I predicted transition to tropical on Sunday (i.e. today). She is strengthening a bit earlier today than I thought...I was thinking she would strengthen to 60 mph by 11 PM tonight instead of 11 AM this morning. If Beryl's trends continue...my general intensity forecast could verify.

Trackwise though...I was still off...

I will be putting another update out around 1:00 PM this afternoon with an updated Beryl forecast included....

it already is in the gulf stream, it is nearing the cooler waters, if it was further south, it would have a better chance of intensifying because the cool shelf is not as large

The New York Weather service in Buffalo is like that, because they actually name their lake effect snowstorms after random topics.

i.e.
2010-2011 lake effect storms were named after "Fish"
2009-2010: Flowers
2008-2009: Snakes
2007-2008: Dogs
2006-2007: insects
ect...

I think this year was types of cows, so the names were: Ayrshire, Beefalo, Canadienne, Dutch Belted, Evolene, ect..

Lake Effect Storm Copernicus from 2002 when the list was after "Famous Scientists"

just went outside, alot of high up moisture clouds rolling in from the gulf..all headed eastward,going to be a big rainmaker over there later on

There is a slight on & off breeze coming out of the West in Gainesville, FL. It is sunny with only a few of those "cotton ball" clouds in the sky. It is nice to see Beryl moisten up as we need the rain badly in North Florida. We should see some of those rain bands come through here by late afternoon.

Remember if any of y'all are coming down to the jax beaches to watch Beryl, they close the bridges with sustained winds of 40mph (not all that much). And there ain't no way off the barrier island from Mayport all the way down to St Augustine except for those 6 bridges. If you do get stuck, let me know and we'll have a hurricane party!!!

According to Jax Pier cam (which I can see from my balcony), the winds are currently out of the north at 11 mph.


Keep us updated. And stay safe. Tropical Storm Winds will arrive shortly at your location.

Ah ok, so she is almost tropical. Doesnt have too much more time though to become fully TS before landfall.

IT APPEARS THAT BERYL
MAY BE TRANSITIONING INTO A TROPICAL CYCLONE.
