Day 2
Valid 12Z Tue Feb 18 2025 - 12Z Wed Feb 19 2025

...THERE IS A MARGINAL RISK OF EXCESSIVE RAINFALL ALONG PORTIONS OF
THE CENTRAL GULF COAST...

Strengthening southwesterly winds ahead an amplifying upper level
shortwave and an associated cold front are expected to draw deeper
moisture into parts of the Gulf Coast, with PWs climbing to around
1.5 inches. This moisture along with increasing lift and
instability may be sufficient for heavy rainfall rates. Models
offer a modest signal for training storms ahead of a surface low
that is forecast to develop and advance east along the coast
Wednesday morning. This may help support localized heavy rainfall,
with some potential for isolated flash flooding, especially in
urbanized areas.

Day 3
Valid 12Z Wed Feb 19 2025 - 12Z Thu Feb 20 2025

...THERE IS A MARGINAL RISK OF EXCESSIVE RAINFALL ACROSS PORTIONS
OF NORTHERN FLORIDA AND SOUTHERN GEORGIA...

Surface low developing along the central Gulf Coast on Day 2 will
continue to track east early in the period, before tracking
northeast along the Southeast Coast later in the day. Training
storms, with potentially heavy rainfall rates fueled by deep 
moisture (PWs 1.5-1.75 inches) ahead of the wave and along its 
trailing cold front, may produce locally heavy amounts and an 
isolated flash flooding threat on Wednesday.
