A tropical wave accompanied by a wind surge crossed the U.S. Virgin Islands and Puerto Rico on July 21st.  Although most of the weather remained south over the Caribbean Sea, flooding from the wave rainfall was reported along both the Rio Grande the Loiza and the Rio De La Plata rivers. In the Northeast, the rain forest of El Yunque also reported high rainfall amounts which generated enough runoff to create some flooding in the municipalities of Fajardo, Naguabo and Rio Grande.  Some minor urban flooding was also experienced in the San Juan Metropolitan area. Around 37 thousand homes were without electric power due to wind gusts causing tree limbs to fall on power lines, around 20 roads in different parts of the island were reported impassable due to flooding induced by poor drainage.
