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.
