...Flash Flood Watch remains in effect from 2 am AST Friday through Saturday morning...
The Flash Flood Watch continues for
* all Puerto Rico...Culebra...Vieques and U.S. Virgin Islands
* from 2 am AST Friday through Saturday morning
* a strong tropical wave will move across the local islands through late Friday. Showers with thunderstorms will continue to spread across the region overnight and Friday. Based on the latest hurricane center guidance...environmental conditions are expected to be conductive for some development during the next day or so while the system moves west-northwestward around 20 to 25 mph.
* Regardless of development...periodic bursts of heavy rainfall are expected across the islands accompanying the tropical wave. Rainfall totals between 4 and 6 inches with locally higher amounts in mountainous terrain are likely during this event. Therefore...there is a high potential for urban and flash flooding through at least Saturday morning.
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 and rock slides 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.
