Hydrologic Outlook

National Weather Service Miami FL

345 PM EDT Wed Mar 20 2024



...Heavy Rainfall Possible Late Week Into Early This Weekend...



A surface low is forecast to develop over the Gulf of Mexico

sometime on Friday and move eastward across portions of the

Florida Peninsula Friday night into Saturday morning. This will

allow for a warm front to move through South Florida on Friday 

afternoon into Friday evening before a cold front moves southward 

through the area Saturday morning. This will lead to couple of 

rounds of rains and thunderstorms over South Florida during this 

time frame.



The forecast soundings are also showing that the precipitable

water values will be around 1.6 to 1.8 inches which is above the 

90th percentile and near the maximum values for this time of year.

This means that heavy rainfall is also possible with the rounds 

of showers and thunderstorms. At this time it looks rainfall 

totals of 3 to 5 inches are possible with locally higher amounts 

possible with any training of thunderstorms.



The ground across South Florida is somewhat dry due to the lack 

of rainfall the last couple of weeks. However, with the locally 

heavy rainfall there could be some isolated areas of flooding with

the showers and thunderstorms, especially where the thunderstorms

train over the same area.
