Flash Flood Watch

Expires 6:00 PM AST on May 25, 2013
Statement as of 10:28 PM AST on May 24, 2013

... Flash Flood Watch remains in effect through Saturday afternoon...

The Flash Flood Watch continues

* for all Puerto Rico... including Culebra and Vieques.

* Through Saturday afternoon

* scattered showers and thunderstorms overnight may pose a risk of
localized heavy rainfall and isolated flash flooding. However...
main threat for widespread heavy rainfall and greater risk of
flash flooding is expected to be Saturday as deeper moisture is
drawn northwestward on east southeast low level winds and begins
to interact with an upper level trough approaching from the
west. Widespread two to four inches of rain appear likely north
of the central Cordillera... eastern Puerto Rico... Culebra and
Vieques. These amounts of rain could fall in a short period of
time leading to flash flooding of small streams and rivers.


Precautionary/preparedness actions...

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.

This product... along with other weather... hydrological and climate
information... is available on the web at http://www.Srh.NOAA.Gov/sju
