D. INLAND FLOODING...
---------------------------------------------------------------------
PUERTO RICO...FLOODS ARE GENERALLY CATEGORIZED BASED ON THE LEVEL OF
THEIR IMPACTS, AND THE EXTREME RAINFALL FLOODING EVENT CAUSED BY
HURRICANE MARIA IN PUERTO RICO CAN BE CONSIDERED AS CATASTROPHIC DUE
TO THE NUMEROUS EVACUATION AND RESCUES PERFORMED, OVERWHELMING
OVERFLOWING OF RIVERS AND TRIBUTARIES, MEDIUM TO LARGE SCALE
MUDSLIDES AND THE EXTENSIVE DAMAGE TO STRUCTURES, AS WELL AS ROADS
AND BRIDGES. IN FACT, STREAMFLOW DATA FROM THE U.S. GEOLOGICAL
SURVEY SHOWED THAT 53 OUT OF 65 RIVER GAUGES MET OR EXCEEDED FLOOD
STAGE. AMONG THESE RIVERS, 30 EXCEEDED MAJOR FLOOD STAGE WHILE 13
REACHED OR EXCEEDED ALL-TIME RECORD LEVEL. WIDESPREAD RIVER FLOODING
WAS OBSERVED ACROSS THE ISLAND, PARTICULARLY ALONG THE SOUTHEASTERN,
NORTHERN AND WESTERN PORTIONS OF PUERTO RICO.

COUNTY            DEATHS           INJURIES             EVACUATIONS
DESCRIPTION
---------------------------------------------------------------------
PUERTO RICO          16            NUMEROUS

DURING A SURVEY OF AREAS ALONG THE PATH OF HURRICANE MARIA CENTER IT
WAS EVIDENT THAT CATASTROPHIC DAMAGE HAD OCCURRED. MARIA`S STRONG
WINDS SPREAD LARGE AMOUNTS OFDEBRIS ACROSS THE ENTIRE AREA. ALL
FULL TREES WERE LEAFLESS, AND THOSE THAT WERE NOT SNAPPED OR
UPROOTED BY MARIA`S STRONG WINDS, LOST MEDIUM TO LARGE BRANCHES.
DURING THE INTERVIEW PROCESS, STORIES AND IMAGES WERE PARTICULARLY
SIMILAR. NUMEROUS LOCALS REPORTED THAT THEY FELT THE GROUND SHAKING
AS MARIA CROSSED THE ISLAND, WHILE MOST WERE AMAZED BY THE FORCE OF
THE UNPRECEDENTED STRONG WINDS THAT NOT ONLY TRANSFORMED THEIR
SURROUNDINGS BUT THEIR LIVES. ALTHOUGH MOST STRUCTURES ACROSS THE
ISLAND ARE BUILT USING CONCRETE AS THE MAIN MATERIAL, COUNTLESS
HOMES AND BUILDINGS SUSTAINED SOME TYPE OF STRUCTURAL DAMAGE.
STRUCTURES WITHOUT A CONCRETE ROOF SUFFERED SOME TYPE OF ROOF DAMAGE
OR IT WAS COMPLETELY BLOWN OFF. NEARLY ALL COMMERCIAL SIGNAGE,
FENCES, AND CANOPIES WERE DESTROYED, INCLUDING LARGE DIGITAL HIGH
DEFINITION BILLBOARDS. THE LAST TIME THAT PUERTO RICO EXPERIENCED A
CATEGORY 4 OR MORE HURRICANE WAS BACK ON 1928 WITH HURRICANE SAN
FELIPE II.
