More than 30,000 people across the Gulf Coast are likely to seek temporary shelter as Tropical Storm Harvey continues to drench southeastern Texas and Louisiana with heavy rains and surging floodwaters. (August 28, 2017) (Sign up for our free video newsletter here http://bit.ly/2n6VKPR)
To put Houston's flooding in perspective, Tropical Storm Harvey is expected to drop as much rain as Baltimore gets in a year — enough to fill the Chesapeake Bay.
National Weather Service meteorologists predict rainfall in some parts of southeast Texas will surpass 50 inches. They said Tuesday afternoon that one rain gauge southeast of Houston was reporting 49.32 inches, a record for a tropical system in the contiguous 48 states.
That is more than the precipitation reported at Baltimore-Washington International Thurgood Marshall Airport in three of the past five years. Average annual rainfall at BWI, Baltimore's point of record, is about 46 inches.
A widespread 25 inches has fallen across Greater Houston. Baltimore has never seen nearly as much rainfall within a month.
About 18 inches of rain fell in Baltimore's wettest month on record, in August 1955, when Hurricane Connie hit.
