...Spring Flood Outlook for South Florida...
...Flood threat is very low for South Florida this spring...

South Florida has seen below normal rainfall since October 2016,
as cold fronts have been mostly dry when they moved through South
Florida. This has allowed for the development of moderate drought
conditions(D1) over the northern portion of South Florida
including the west coast metro area. The rest of South Florida
has also developed into Abnormally Dry Conditions (D0), except for
the southeastern areas of South Florida where no drought
conditions exist at this time.

metro areas are running near normal levels.

As of March 1st, the Keetch-Byram Drought Index (KBDI) was
500 to 550 over the eastern half of South Florida with the
western half of South Florida in the 550 to 600.
This puts all of South Florida in a moderate risk of wild fires.


The South Florida Water Management District has continued the
yearly water restriction for all of South Florida. For more
information on the water shortage conditions, please visit the
South Florida water management web site at WWW.SFWMD.GOV/WATERWATCH.


High pressure will slowly move east across the Southeastern
United states this weekend and into the western Atlantic waters
by early next week. This will allow for an breezy to windy
northeast wind flow over South Florida with a few showers
affecting the east coast metro areas.

The Climate Prediction Center`s Precipitation outlook for the
next 8 to 14 days calls for an below normal rainfall chance
across South Florida. The long term outlook for March through
May is for an equal chance of above or below normal rainfall
across South Florida.

The next update on the drought conditions for South Florida will
be around the middle of March, unless conditions change before
that time. Stay tune to NOAA weather radio and other local media
for further details and updates.
