The National Weather Service on Sunday released a dire warning about flooding in Houston, Texas.
“This event is unprecedented & all impacts are unknown & beyond anything experienced. Follow orders from officials to ensure safety. #Harvey,” the NWS tweeted Sunday.
It says that some areas in southern Texas will experience about 40 inches of rain, triggering long-term flooding
Tropical Storm Harvey has caused chest-deep flooding on some streets in Houston as rivers and channels overflow their banks. After up to 30 inches (76 cm) of rain in some parts of the fourth most-populous U.S. city, the storm is expected to dump 12 to 25 more inches (30-63 cm) over the next few days, the National Weather Service forecast. The total could reach 50 (127 cm) inches in some coastal areas of Texas by the end of the week, or the average rainfall for an entire year.
