A storm system that wallopped California and Texas with rain earlier this week is moving east across the United States, likely bringing severe weather from Oklahoma to Mississippi.

The National Weather Service (NWS) is predicting possible flash flooding and severe weather for the Lower Mississippi Valley Thursday through the end of the week.

Parts of eastern Texas through Arkansas should prepare for possible strong winds, hail, isolated tornadoes, tree damage, and power outages.

The greatest risk for tornadoes will be centered around Louisiana, according to AccuWeather. The potential for weather-related damage extends all the way south to New Orleans.

The southeast is the most likely target for heavy rain, potentially more than five inches, which could cause flash flooding in the area.

"Runoff from the heaviest rain may eventually feed into the larger rivers that are already out of their banks across the lower Mississippi River Valley and cause additional rises or slow the receding river levels," AccuWeather senior meteorologist Kristina Pydynowski said.

Flights from Houston, Dallas, and Miami have been affected by the weather, according to FlightAware. No airline has yet issued a travel waiver for the storms. Passengers who are traveling through the area on Thursday and Friday should contact their airline for up-to-date flight information.

Rain will move eastward across the country through the weekend, with the potential to hit the major northeastern cities by Saturday, according to CNN. However, by that time, the storm's intensity should have slowed and will likely not cause major damage.
