...Late Week/Weekend: Heavy Rainfall Becoming More Likely with Flooding Possible...

This hazardous weather outlook is for South Florida.


Thunderstorms: Isolated to scattered thunderstorms are possible over
South Florida with the best coverage over the Lake Okeechobee and
northeast areas of South Florida. The main concern will be
lightning, gusty wind, and street flooding in urban areas due to poor
drainage for all metro areas on both coasts.

Flooding: There is a slight chance of urban flooding of the roadways
for the coastal metro areas, especially in typical flood prone
areas, low lying areas, as well as areas with poor drainage with any

Coastal Flooding: Coastal flooding is also possible during high
tides due to the spring tides of the full moon.

Wind: Some of the storms could produce strong wind gusts of 45 to 50
mph this evening, mainly in the interior.

Waterspouts: There is a slight risk of waterspouts for all South
Florida waters.


A frontal boundary could stall out somewhere over the region by mid
week, which could lead to increased chances of showers and
thunderstorms through the end of the week into the weekend. At the
same time, a coastal trough could set up over the eastern areas of
South Florida, a possible tropical low develops over the Western
Caribbean and moves west northwest into the Northwest Caribbean. This
will allow for deep tropical moisture to work into South Florida
late this week into this weekend which could enhance the potential
heavy rainfall along with some flooding.

The spring tide (high astronomical tide) may bring coastal flooding
to the east coastal areas through this weekend.


Widespread spotter activation is not anticipated, however individual
spotters are encouraged to report winds and flooding to the National
Weather Service forecast office in Miami. Please relay any information
about observed severe weather to the NWS while following all local,
state, and CDC guidelines.
