...INCREASED RISK OF FLOODING FROM TUESDAY THROUGH THURSDAY FOR
PUERTO RICO AND THE UNITED STATES VIRGIN ISLANDS...

A deep layered-trough and accompanying frontal boundary will
approach the islands by late Monday into Tuesday, pulling moisture
from the south into the local islands. This will increase the
risk for flooding, rapid river rises and mudslides across Puerto
Rico and for the U.S. Virgin Islands.

Based on the latest guidance, squally weather will begin over
Puerto Rico as soon as Monday night or very early on Tuesday. The
swath of moisture will then spread eastward toward most of Puerto
Rico, and reaching the U.S. Virgin Islands by late Tuesday. So
far, the strongest showers and thunderstorms are expected both on
Tuesday and Wednesday, but some of this activity could linger on
Thursday over Puerto Rico, and early Friday over the Virgin
Islands.

Rainfall accumulations should range from 2 to 4 inches,
especially for the southern, interior and eastern sections of
Puerto Rico, and everywhere in the Virgin Islands. Isolated
higher amounts, up to 6 inches are possible in these areas as
well.
