The Tropical Atlantic is Starting To Bubble
Posted by Dan Satterfield
The tropics are getting more active now.
An old forecaster saying is “there’s almost always a hurricane on Atlantic weather map on Labor Day. We have Tropical Storm Florence in the far west Atlantic and a possible developing depression near Florida on this Labor day 2018. Both of which will need to be watched. It looks like the switch has been turned on in the Atlantic Basin as a more favorable MJO pattern arrives.
Florence looks healthy in the Atlantic but it will soon run into a lot of wind shear in spite of finding warmer water underneath it. The waters in the main development region (MDR) have been cool all summer (and still are) but any storm that gets close to the U.S. or Carribean will find very warm waters.
The September heat wave on the East Coast will continue this week and that strong high pressure could keep Florence from recurving and it MIGHT be a threat in around 8-9 days. The hurricane season peaks on September 10th. Right on time.
One last thing: If you see raw model guidance being shared online showing doom and gloom. Ignore it. It’s way too soon and all models are WRONG. Sometimes though, they provide useful information.
