... Flash Flood Watch now in effect through Wednesday evening...
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... north Central... Northeast... Ponce and vicinity... San Juan and vicinity... southeast... southwest and Vieques. In Virgin Islands... St Croix and St. Thomas/St. John/adjacent islands.
* Through Wednesday evening
* abundant tropical moisture... associated with the newly formed Tropical Depression Fifteen located near latitude 14.8 north... longitude 69.6 west... will lift northwards and bring occasional bands of showers and strong thunderstorms with gusty winds across the U.S. Virgin Islands... and all of Puerto Rico through Wednesday evening. Given this scenario... heavy rains across the local islands during this prolonged period will result in significant rainfall accumulations over the next several days. Residents and visitors and motorists can therefore expect areas of moderate to heavy rainfall... with isolated rainfall totals ranging between 5 and 10 inches of rainfall through Tuesday... then increasing to 15 to 30 inches or more of accumulative rainfall through the end of the week.The depression is forecast to eventually turn towards north northeast across Puerto Rico and the remainder or the local islands by mid week. Due to already saturated soils... across much of Puerto Rico... any additional heavy rainfall will likely result in areas Rapid River rises and of flash flooding... along with mudslides/debris flow.
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.
Please stay tuned to NOAA Weather Radio... local TV... radio or your cable television provider for later statements and possible warnings.
