Radar

[Mar 12] During the overnight hours, brief showers will mostly impact the eastern portions of the islands. Please exercise caution on roadways, as ponding of water on roads and in poorly drained areas could result in slippery conditions. Reduced visibility may also occur at times in areas experiencing the heaviest showers. Durante las horas de la noche y madrugada, aguaceros breves impactarán principalmente los sectores del este de las islas. Se recomienda precaución en las carreteras, ya que la acumulación de agua en las vías y en áreas de drenaje deficiente podría provocar condiciones resbaladizas. La visibilidad también podría reducirse en ocasiones en las zonas donde ocurran los aguaceros más fuertes.
