Multiple cells and clusters of thunderstorms during the pre-dawn hours into the morning commute on June 20th dropped measured and estimated rainfall between 5 and more than 8 inches in western Cameron County, which caused widespread flooding between La Feria, Harlingen, San Benito, and other locations. The flooding produced locally 2 to 4 feet of water depth, with Santa Rosa through La Feria particularly hard hit. Interstate 2 frontage road was closed from Harlingen to McAllen due to the intense rainfall, which fell at an estimated rate of 2 to 3 inches per hour in a few spots for 2 to 3 hours - and on top of prior rainfall earlier in the week.||Detailed damage for this particular event was not known, though total damage through multiple agencies along with standard doubling for uninsured
