Hydrologic Outlook

1250 PM AST Sat Aug 10 2024

...A TROPICAL DISTURBANCE IS EXPECTED TO DEVELOP AND BRING HIGH
CHANCES OF HEAVY RAIN AND FLOODING TO PUERTO RICO BEGINNING
TUESDAY...

A significant increase in moisture will be caused by a developing
tropical disturbance located 1400-1900 miles east southeast of
Saint Croix during its passage across the local area Tuesday
afternoon through Wednesday.

Moisture and rainfall will increase on Tuesday and become heavy by
Tuesday night as showers and thunderstorms from this system bring
amounts up to 6 inches across the area. At this time the heavier
amounts are expected in the mountains, with the coastal plains and
the U.S. Virgin Islands receiving 2-4 inches and northwest Puerto
Rico around 1-2 inches. Locally heavier amounts are possible, but
these are preliminary estimates. Showers with heavy rain may also
linger through Wednesday night.

Prolonged periods of moderate to locally heavy rainfall will
enhance the risk of flooding, river rises, and mudslides. It is
possible that some rivers overflow, and that flash flooding will
develop as well. Forecast users are advised to stay tuned to
weather updates, especially those that live or commute in flood
prone areas.
