Description: 
ESFSJU An upper-level trough moving across the northeast Caribbean combined with abundant moisture will result in showers and thunderstorms across the local island Friday and Saturday. Based on the latest guidance, there is a chance to observe periods of showers and thunderstorms Friday and Saturday. The areas expected to receive the highest rainfall totals include northwest, central and the eastern coastal areas of Puerto Rico as well as Vieques, Culebra and the US Virgin Islands. Across these areas there is a moderate chance(40-60%) to observe 2 to 4 inches with locally higher amounts of up to 6 inches. Due to already saturated soils and rivers and tributaries running well above normal levels, there is a risk for flooding across Puerto Rico and the US Virgin Islands on Friday and Saturday. Any prolonged period of heavy rainfall will result in urban and flash flooding, river flooding and mudslides particularly across central and east Puerto Rico where rainfall has been abundant over the past month.
