Flood · Puerto Rico

Road #2 In Vega Alta was close due to flooding.

A very strong Tropical Wave moved over Puerto Rico during July 18, 2013. This wave brought deep topical moisture from the Intertropical Convergence Zone(ITCZ) through the area. These features, in combination with a southeast wind flow and local effects produced torrential rainfall, mainly along the north coast of Puerto Rico. Streamers from El Yunque National Forest developed in the afternoon on July 18, 2013, and were moving very slowly toward the northwest, which affected the San Juan Metropolitan area. The streamers redeveloped over the same area, and brought with it torrential rainfall which led to serious flooding across the San Juan Metro Area. The total rainfall accumulation exceed 9 inches over San Juan. Rainfall totals between 3 to 5 inches were also reported across the North Central section of Puerto Rico. Several reports of flooding were received from the municipalities of San Juan, Carolina, Bayamon and Guaynabo with hundreds of residences and roads affected by the waters. Overall losses were estimated over 1 million dollars across the San Juan Metropolitan area.
