This trough is producing a southwesterly flow over the state of Florida which

is enhancing the rain and late afternoon storm development once again today.

TROUGH OF LOW PRESSURE LOW CHANCE FOR DEVELOPMENT

A trough of low pressure in the middle levels of the atmosphere is producing fasting moving showers over the Florida.  Atmospheric conditions and proximity to land is hindering development at this time.  This system has a low chance 10% for sub-tropical or tropical development.  After reviewing models they are also suggesting a low chance for development.  Main concern is heavy rains and storms at time.

Special Tropical Weather Outlook

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

1. A trough of low pressure located over the northwestern Bahamas is
producing disorganized shower and thunderstorm activity.  Little
development is expected during the next couple of days as the
system moves generally northwestward toward the Florida Peninsula.
Subsequently, some slow development is possible as the disturbance
turns northeastward and moves over the western Atlantic.
Regardless of development, locally heavy rains are possible over
portions of the Bahamas and the Florida Peninsula during the next
couple of days.  The next Special Tropical Weather Outlook will be
issued by 10 AM EDT Thursday, or sooner if conditions warrant.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.

Forecaster Beven

Strong easterly winds is beginning to draw in moisture on shore the east coast of Florida as this trough tracks west-northwest to a northwest.  These showers will be fast moving and at times could be heavy. 

Development is not out of the question, but if it were to occur, it would be as this system re-curves back to the northeast and over the west Atlantic waters. RTW

A NON TROPICAL DISTURBANCE IN THE BAHAMAS

A non tropical disturbance near the Eastern Bahamas associated with a mid to upper level low could enhance rain and storm chance for the Bahamas and Florida in the coming days.

Could this system become a sub- tropical storm or tropical depression?  That can't be ruled out,  however, models are not hinting at strong development at this time.  I will monitor it closely as it tracks west-northwestward.

Will begin regular tropical updates starting May 15, 2019.  So check back daily after the May 15 for your full tropical updates.
