Weather Blog: Beryl is back as a subtropical storm

SOUTHWEST FLORIDA -

No, we're not kidding. Beryl is back from the dead. 

After eight days without a center, the remnants of Beryl formed up again over the warm waters of the Western Atlantic. Beryl is now producing a small region of weak tropical storm force winds up to 40 mph with gusts as high as 50 mph. Beryl shows an organized but lopsided structure on satellite images.

 

Beryl is now a subtropical storm, a kind of hybrid storm system. A large bend in the jet stream, a belt of winds high up in the atmosphere, has gotten a hold of Beryl below it. Beryl is now feeding off of the temperature contrast on either side of the jet stream as well as the warm water it's passing over. Tropical storms only feed off warm ocean temperatures, so Beryl is classified as a subtropical storm because of this difference. This is the second named subtropical storm we've had this season, the first being Alberto in April. 

Beryl's second life will be even more short-lived than the first go around last week when it became a hurricane. Beryl is being helped along because it's still in warm Atlantic waters bordered by the Gulf Stream current. Beryl will track north of the Gulf Stream on Sundayand begin to slide over waters 15 to 30 degrees cooler than where the storm passed Saturday. This will quickly spell the end of Beryl, this time for good. Early in the coming week the remains of Beryl will track over the same region of Newfoundland that was just hit by Chris on Thursday.
