POTENTIAL TROPICAL CYCLONE 9, LATER CLASSIFIED AS TROPICAL STORM
ISAIAS, MOVED WEST-NORTH WEST ACROSS THE EASTERN CARIBBEAN WATERS
BETWEEN WEDNESDAY JULY 29TH AND THURSDAY JULY 30TH. THE NORTHERN
HALF OF THE TROPICAL SYSTEM MOVED OVER PUERTO RICO AND U.S. VIRGIN
ISLANDS AREA GENERATING SQUALL LINES ACROSS ALL THE ISLANDS.
ALTHOUGH THE IMPACTS OVER THE U.S. VIRGIN ISLANDS WERE MINIMAL,
WINDY CONDITIONS AND RAPIDLY MOVING SQUALL LINES WERE REPORTED
ACROSS THE LOCAL ISLANDS. THE ENTIRE BIG ISLAND OF PUERTO RICO
REPORTED DAMAGES, HOWEVER THE MOST SIGNIFICANT DAMAGES ASSOCIATED
WITH THIS TROPICAL EVENT WERE REPORTED OVER THE EASTERN AND WESTERN
PORTIONS OF PUERTO RICO. STRONG WINDS AFFECTED PUERTO RICO WITH
MAXIMUM SUSTAINED WINDS OF 30 TO 40 MPH AND GUSTS TO AROUND 60 MPH.
MOST OF THE STRONGEST WIND GUSTS WERE ASSOCIATED WITH SQUALL LINES
ALONG THE COAST AND HIGHER ELEVATIONS. DAMAGE REPORTS ASSOCIATED
WITH THESE SQUALLS INCLUDED MULTIPLE BILLBOARDS, TREES AND POWER
POLES/LINES BEING KNOCKED DOWN, AS WELL AS ROOFS BEING SIGNIFICANTLY
DAMAGED. SEVERAL FLOODS WERE REPORTED WITH THIS TROPICAL EVENT. MAIN
AND SECONDARY ROADS WERE CLOSED BY FLOODING. DOZENS OF HOMES WERE
AFFECTED BY THE FLASH FLOODS AT THE RIO HONDO AND QUEBRADA GRANDE
SECTORS IN MAYAGUEZ. SEVERAL LANDSLIDES WERE ALSO REPORTED MAINLY IN
STEEP TERRAIN ALONG LA CORDILLERA CENTRAL AND OVER THE SIERRA DE
