30 DRAINAGE FROM ABOVE LOOP 410 AND BROOKS AFB CUTS STREETS AND AREAS BELOW LOOP 410 IN THE SAN ANTONIO RIVER FLOOD PLAIN OFF - SEVERAL HOMES HAVE A FEW FEET OF WATER IN THEM
27 THREE RESIDENCES BELOW LOOP 410 ON THE LEFT BANK FLOOD - ROADS INTO THE AREA ARE FLOODED AND DANGEROUS
26 MAJOR FLOODING REACHES SLABS OF RESIDENCES ON THE LEFT BANK BELOW SOUTHEAST LOOP 410 - ROADS AND STREETS NEAR THE SAN ANTONIO RIVER ARE SEVERELY FLOODED AND VERY DANGEROUS
23 MODERATE LOWLAND FLOODING OF LOWEST ROADS AND BRIDGES IN THE FLOOD PLAIN MAKE AUTO TRAFFIC VERY DANGEROUS - LOWEST HOMES BELOW LOOP 410 IN THE LEFT FLOOD PLAIN ARE THREATENED
20 MODERATE LOWLAND FLOODING OF ROADS AND STREETS BELOW BROOKS AFB AND IN THE FLOOD PLAIN NEAR LOOP 410 MAKES AUTO TRAVEL IN THE FLOOD PLAIN VERY DANGEROUS
