The wider storm

A nighttime core rain event occurred in the Laredo vicinity during the early morning hours of July 27th. A weak upper level low pressure area moved across the western Brush Country during the night and interacted with deep tropical moisture over the area. Thunderstorms developed over the eastern part of Webb County and slowly moved toward Laredo a few hours after midnight. Very heavy rainfall of 5 to 8 inches occurred within a 3 hour time period over the northeast portion of Laredo. This produced flooding in a residential area on the northeast side of Laredo. Several high water rescues were performed with motorists stranded from Interstate 35 to Loop 20 on the northeast side of Laredo. One person was evacuated from her home due to rising water. Around 100 homes received damage from flood waters in northeast Laredo.
