Rain Train Continues

Plenty of tropical moisture keeps aiming for South Florida and may not stop until Monday at the earliest. 

This is the LIVE radar showing where the rain is headed as well as the intensity of the downpours.


The green and yellow areas represent moderate rainfall while the redder color shows the heaviest of the rain. 

South Florida, for that matter the rest of the state, is caught between two weather features that will keep the area soggy over the next 48 - 72 hours at least.


Why so much rain?

Here's an old school weather map showing "Alberto" with the red icon in the Gulf, and two vertical lines near our state, one by SW Florida and the other near the Bahamas. 

Those represent the westernmost edge of high pressure sitting in the Western Atlantic.  

"Alberto's" winds come out of the Southwest, while the winds from the high, come from the Southeast. 

This combo acts as a straw drawing all the moisture from the Tropics here. They will conspire to keep South Florida with high rain chances through Memorial Day.

What advisories are in place for South Florida?


Many areas on Saturday had between half an inch to over an inch and a half of rain. With more expected for the rest of the holiday weekend, a flood watch is in effect at least thru Sunday across the Mainland. It may get extended by NWS Miami, if accumulations continue to go up.
The above graphic illustrates other watches and warnings in place.

What can we expect?
"Alberto's" moisture will get focused on South Florida starting Saturday night. This could lead to some strong thunderstorms and squally weather. We could also get:
  • Possible tornadoes from Saturday night through Sunday 
  • Coastal waters will be rough with possible waterspouts
  • High risk of Rip Currents
  • An additional 3 - 4 inches of rain possible through Monday
  • Some gusty winds up to 40 mph that can topple weak trees and cause power outages

The latest on Alberto
It will move northward across the Gulf on Sunday dispersing plenty of rain everywhere. The wind will pick up even more across Southwest Florida, with choppy seas and minor coastal flooding.


It is forecast to make landfall somewhere between Panama City west to the Mississippi coast sometime late on Monday.


These are the advisories in place for the west coast of Florida.
This is a great example of how even a system that is not that healthy and far away can impact our area with winds and rain.  Stay dry
