The National Weather Service urged people to avoid travel if a flash flood warning was in place for their area.

Flash floods are occurring across the U.S., from Texas to New Jersey. Here's what you should know as risks escalate.

Early on Thursday morning the National Weather Service's Lake Charles office announced that it would be expanding the flash flood warning that previously went as far west as Vermillion Parish to include Calcasieu, Cameron, Allen, Jefferson Davis and Beauregard parishes. The watch is in effect from 7 a.m. on Thursday to 7 p.m. on Saturday.

The Missouri River is not expected to reach any flood stage in Kansas City, but is predicted to cause moderate flooding downstream in Napoleon and Miami, Missouri. The major river has already risen 5 feet, and is forecasted to rise another 3 feet before its crest at around 7 p.m.

Hundreds of New Jersey homes were damaged by flooding Monday​, and many families are just beginning the process of filing insurance claims.

The $3 billion "Mass Ready Act" would be a historic investment in climate-readiness, state officials say. Advocates are cheering — but would like even more.

Lubia Estevez and Forest Whitlock, both women in their 60s, died Monday night when they were traveling during an intense storm and their car ended up in a ditch before being washed away. Their families are now sharing the kind of people they were.

The risk for flash flooding won't just be confined to today, as data shows the risk for flash flooding remaining in place Thursday, Friday, Saturday, and likely on Sunday too. There will be some big gaps in the rain, though, including most of Friday, looking dry and pleasant.
