The wider storm

An upper level trough combined with strong daytime heating and very ample moisture to produce numerous showers across the northern half of Puerto Rico. U.S.G.S sensors recorded between 2 to 4 inches across these areas. In a 24 hour period, a U.S.G.S sensor recorded 3.29 inches in Isabela, 2.19 inches in Camuy, and 2.25 inches near the Tanama river in Utuado. Heavy rains inland between Orocovis, Barranquitas and Coamo Arriba caused the Coamo river to overflow its banks.
