Flash flooding threatens Houston, again, as heavy rain continues in central US

Heavy rain is soaking the central U.S. this week, delivering a dangerous flooding threat in the Houston area. The exceptionally wet set of days continues Wednesday as the parade of storms is expected to dampen as many as 40 states in the Lower 48, with widespread rain and thunderstorms continuing into the weekend. The heavy rain will spread north on Wednesday through southeastern and eastern Texas, Oklahoma and Arkansas, continuing the flood risk there.
