Tropical Storm Harvey has been downgraded to a tropical depression but not before creating a new weather record in the United States.
Climatologists say Harvey is the worst rainfall event ever with 1318 mm (51.88 inches) of rain recorded at Cedar Bayou, Texas beating the previous mark of 1219 mm (48 inches) in Medina, Texas from Tropical Storm Amelia in 1978.
Thousands of residents could still be stranded and an estimated 40,000 homes have been destroyed by the storm in the Houston area.
Heavy rain is now moving over Louisiana, Mississippi, Arkansas and Tennessee with some areas expecting more than 200 mm.

More than 30 people have been killed by a series of tornadoes across the American South since Sunday.
The states of Arkansas and Mississippi have been hardest hit with hundreds injured, neighborhoods flattened, homes reduced to splinters and trees snapped like twigs.
Tornadoes have also knocked out power to tens of thousands across several states.
Forecasters were calling for more severe conditions today especially near the U.S. Gulf Coast.

For many in Southern Ontario, this wintry wallop was the first major snowstorm of the season dumping about 15 cm of snow on Windsor, Toronto and Hamilton with 20 cm in Ottawa and 30 cm in Kingston.
Montreal could receive as much as 40 cm of snow while Quebec City can expect about 20 cm.
The storm actually originated in the American South dropping rare post-Christmas snow on cities like Dallas, Texas and Little Rock, Arkansas.
After hammering the U.S. Northeast with snow and rain, the storm is now moving into New Brunswick and Nova Scotia with snow, strong gusty winds and rain along the Atlantic coast.
