As crews search for missing people after flash floods killed at least 120 in Texas, cities across the U.S. grapple with rising flood waters.

Thursday's rain was a highly localized event. The highest impact was only felt over a 5-to-10 mile area south of Boston.

At 3:47 p.m. on Thursday, the NWS Newport/Morehead City NC released a flash flood warning in effect until 7 p.m. for Dare County.

Radar shows the rain is coming down at a rate of a half-inch to 1.5 inches per hour, according to the National Weather Service.

With rain coming down so fast, storm drains couldn't handle the deluge of water. On Interstate 93 in Quincy, all were lanes closed at one point because of extreme flooding during rush hour. At least five cars were stuck on the highway until the water receded.

Back-to-back flooding disasters in recent years — in Texas, New Mexico and Kentucky, among many others — have showed that preparing for flash flooding is a new necessity as the planet warms.
