New Depression and Rain for So FLA

As of 11 am Thursday morning, NHC started issuing advisories on NEW Tropical Depression #6.
It is almost 900 miles West of the Cape Verde Islands with 35 mph winds and moving into the middle of the Atlantic Ocean.  It will slowly gain strength as it moves on a northwest track.

This is what NHS says about possible intensity:

The depression is currently in an environment of light vertical wind shear.  The large-scale models forecast some increase in southerly shear after 24 hours, which should persist through the
end of the forecast period.  

Despite the shear, the intensity guidance forecasts slow but steady strengthening.  The official forecast follows this scenario and is a blend of the SHIPS model and
the intensity consensus.


Forecast cone:

The forecast cone keeps it over open waters slowly intensifying until it reaches hurricane status in a few days.

By the middle of next week Bermuda should start paying attention in case it drifts their way.

It should only be a worry for the shipping lanes.



Florida Rain: 
Closer to home there is a disturbance just east of Florida which the National Hurricane Center is following. You can see the small area of clouds over the Northwestern Bahamas .

They are giving it a 30% chance it could develop into a depression or a tropical storm over the next few days.  It continues to move west spurred along by the Bermuda High.  Even if it doesn't develop, it is expected to cause rainy days at least through the weekend.



What can we expect?:
Most models agree that conditions for growth will remain unfavorable through the end of the week. It should cross South Florida on Friday.  Nothing is ever certain with intensity forecasting, so check back from time to time to make sure it will not surprise us.



NWS says our main impact should be rain. Some could start arriving late today and stick around through the weekend, depending on how fast it moves. We may see ponding of water on roadways  that could lead to street flooding.

The NWS office adds:
LOCALIZED FLOODING WILL REMAIN POSSIBLE FRIDAY INTO THE WEEKEND
AS A WEAK AREA OF LOW PRESSURE MOVES THROUGH FROM EAST TO WEST. IN
ADDITION TO THE RAINFALL...SCATTERED TO NUMEROUS THUNDERSTORMS
WITH FREQUENT LIGHTNING AND GUSTY WINDS WILL REMAIN POSSIBLE EACH
DAY.
