Heavy Rain Threat

The risk for excessive rainfall and flash flooding is highest today and continues into Friday for areas along and south of the I-10/12 corridor. High rainfall rates in excess of 2-3 inches per hour will likely lead to ponding of water in low lying and poor drainage areas at times. Some roads may become impassable, especially around underpasses. In localized areas of heaviest rainfall, some low lying structures may become flooded. Flash flood threat on Saturday is conditional on how much rain falls on Thursday and Friday. Stay weather aware, have multiple ways to get warnings, and avoid flooded roadways.
