NWS: Valley sees historic rainfall of 20 inches

HARLINGEN, Texas (ValleyCentral) — A historic storm that moved through the Rio Grande Valley last Thursday broke records dating back to the last century.

According to the National Weather Service, the storm wiped through Valley cities and towns that continue to recover after receiving up to 20 inches of rain within three days.

Residents may be wondering what caused the storm, as it came at an unexpected and sudden time.

Chief Meteorologist Bryan Hale says the cause revolves around an area of low-pressure moving northeast across Mexico.

Bryan says the mid-level low was supposed to scoop up moisture and bring it over the Valley to energize the moisture into clouds and bring up to four inches of rain.

Instead, the area of low pressure moved too far east at a slow and strong pace, producing heavy rainfall.

As of March 31, hundreds were rescued from floodwaters, and many homes received inches of water inside.

All Rio Grande Valley counties impacted by the severe storm are under a disaster declaration as recovery efforts are underway.
