... Flash Flood Watch now in effect through Sunday afternoon...
The Flash Flood Watch is now in effect for
* portions of Puerto Rico and Virgin Islands... including the
following areas... in Puerto Rico... central interior... Culebra...
eastern interior... Mayaguez and vicinity... north Central...
Northeast... northwest... Ponce and vicinity... San Juan and
vicinity... southeast... southwest... Vieques and western interior.
In Virgin Islands... St Croix and St. Thomas/St. John/adjacent
* Through Sunday afternoon
* showers and thunderstorms this afternoon and early evening will
pose a risk of localized heavy rainfall and isolated flash
flooding. Deeper moisture is being drawn over the area on east
southeast low level winds and will continue to interact with an
upper level trough approaching from the west. Widespread areas
of one to three inches of rain appear likely across central...
northern... and eastern Puerto Rico... with one to two inches
possible over Culebra and Vieques and the U.S. Virgin Islands.
These amounts of rain could fall in a short period of time
leading to flash flooding of small streams and rivers. The
current and expected atmospheric conditions are conducive for
showers and thunderstorm development again on Sunday across the
local islands. Given soil saturation and the amounts of rain
expected this afternoon and evening... any significant rain on
Sunday will cause additional flooding.
* Expect rapid rises in small streams or guts and rivers... with
mudslides possible in steep terrain.
A Flash Flood Watch means that conditions are favorable for heavy
rain across the watch area... which may lead to flooding. If you are
in the watch area... check your preparedness requirements...
especially if you have interests along area rivers. Keep informed...
and be ready for quick action if flooding is observed or if a Flash
Flood Warning is issued.
People in the watch area should continue to be aware of the
possibility for heavy rainfall. Avoid low lying areas... and be
careful when approaching Highway dips and underpasses. The heavy
rain could also cause mudslides in areas of steep terrain.
Stay tuned to NOAA Weather Radio... local TV... radio or your cable
television provider for later statements and possible warnings.
