Tropical Storm Harold has hit the southern tip of the US state of Texas with damaging winds and heavy downpours as forecasters warn of possible flash flooding, minor damage and power outages.
Some 1.3 million people in southern Texas and the Rio Grande Valley area are under a warning as the storm - with winds of 80km/hr - made landfall on Padre Island, the National Weather Service (NWS) said.
Heavy downpours are expected to continue to fall at a rate up to 5cm an hour throughout the day, forecasters added.
The storm could produce coastal flooding and flooding along rivers, on roads and in poor drainage areas.
Strong winds have the potential to cause minor damage to homes and infrastructure, the NWS said.
It also warned of possible power and communications outages.
Some 7,500 homes and businesses in southern Texas were without power as Harold arrived in the area, according to Poweroutage.us.
