..ARLENE DOWNGRADED TO A DEPRESSION..

 

Well as we expected upper level shear and dry air is doing a number on what was once weak tropical storm Arlene.  Post Tropical Storm Arlene has been downgraded to a depression and satellite imagery shows a circulation void of convection (thunderstorms).  With out the thunderstorms surrounding the center of circulation this system cannot strengthen further.  Showers and storms are far out away from the center to the northwest over Florida east coast.  Some of these storms were severe in nature and prompted flood advisory due to the heavy downpours.  We could see a few more of those showers as the low tracks east-northeast over the Florida straits.

UPDATE 0200 PM EDT...A FLOOD WATCH EXTENDED THROUGH SUNDAY EVENING!

..NHC...AIR FORCE HURRICANE HUNTERS INDICATE DEPRESSION HAS STRENGTHENED INTO TROPICAL STORM ARLENE...

 


TROPICAL STORM ARLENE FORM IN THE EASTERN GULF OF MEXICO FIRST NAME STORM OF THE SEASON.  ARLENE HAS GATHERED MORE MOISTURE AS SEEN ON WATER VAPOR IMAGERY.  ARLENE HAS A MUCH LARGER CLOUD CANOPY AND THE MOISTURE IS BEING PUSHED OVER SOUTHERN FLORIDA.  SO THE CHANCES FOR HEAVY RAINS ARE INCREASING IF THIS CONTINUES.  I STILL THINK THAT ARLENEN WILL BE A SHORT LIVED STORM SYSTEM.  I CONTINUE TO MONITOR FOR YOU!

FLOOD WATCH EXTENDED FOR SOUTH FLORIDA THROUGH SATURDAY EVENING!!

..0200 PM EDT STORM INVEST 91L FORMATION CHANCE UPGRADED TO 70% HIGH FOR A DEPRESSION OR SHORT LIVED TROPICAL STORM TO FORM AT ANYTIME..

Satellite imagery continues to show that this disturbance has become better organized this morning and early afternoon.

We could see a depression or tropical storm form at any time today. If it does develop, it will be a short-lived storm as it tracks southward in the coming days. 

Dry air to the south of this system and upper-level winds in the coming days should keep INVEST 91L from becoming a stronger system.

The counterclockwise circulation will enhance the rain and storms over the state of Florida, and a flood watch remains in effect until Friday evening. The flood watch coverage area map below is courtesy of the National Weather Service in Miami, Florida.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Thu Jun 1 2023

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

1. Northeastern Gulf of Mexico (AL91):
Recent satellite wind data, along with buoy and ship observations 
indicate the area of low pressure over the northeastern Gulf of 
Mexico has a broad but well-defined circulation with maximum 
sustained winds of about 35 mph. Shower and thunderstorm activity 
associated with the low is also showing signs of organization. 
Environmental conditions remain marginally favorable for additional 
development, and if these trends continue, a short-lived tropical 
depression or storm is likely to form as soon as this afternoon. The 
system is likely to meander over the northeastern Gulf of Mexico 
through tonight but begin a slow southward motion on Friday. By 
this weekend, environmental conditions are forecast to become 
unfavorable for additional development as the system continues 
moving southward, likely remaining offshore over the Gulf of Mexico. 
An Air Force Reserve Hurricane Hunter aircraft is scheduled to 
investigate the system later this afternoon. 

Regardless of development, locally heavy rainfall could occur over 
portions of the Florida Peninsula through this weekend. Additional 
information on the rainfall and flooding potential can be found in 
products issued by your local National Weather Service forecast 
office and Excessive Rainfall Outlooks issued by the Weather 
Prediction Center.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 7 days...high...70 percent.
