streams... low lying and urban areas. Up to three inches of rain is
likely in isolated locations of central interior Puerto Rico until 4
PM. A Flash Flood Watch is in effect for the entire island... please
stay alert and take action if a Flash Flood Warning is issued.
Most flood deaths occur in automobiles. Never drive your vehicle into
areas where the water covers the roadway. Flood waters are usually
deeper than they appear. Just one foot of flowing water is powerful
enough to sweep vehicles off the Road. When encountering flooded
roads make the smart choice... turn around... dont drown.

* Through late tonight
* a deep trough extending from the surface to the upper levels of
the atmosphere in combination with deep moisture will continue
to favor the development of numerous showers and thunderstorms
throughout the day. The heaviest rainfall is expected across
the St. Thomas and St. Johns through noon today. Additional
thunderstorm development is likely across northern sections of
Puerto Rico later this afternoon as daytime heating helps
destabilize atmosphere.
* Flooding may cause local rivers to rise rapidly especially along
the north coast... north coastal plains and northern foothills.
Flash flooding is also occurring in St. Thomas and St. Jonhs.
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.
