Bronx residents are dealing with the remnants of a powerful storm that blew through the city Wednesday morning.

Drivers were wading through high waters across roadways. Straphangers also experienced heavy delays on subways, including the 1, 2, 3, 4, 5 and 6 trains. Delays eased for the evening rush hour.

Meanwhile, Mayor Michael Bloomberg held a news conference in Brooklyn about a possible tornado touching down in the neighborhood of Bay Ridge. The National Weather Service later confirmed the storm was a tornado packing winds of up to 135 mph.

Bloomberg said one woman died on Staten Island when her car got stuck and another driver hit her. Bloomberg said the driver, who had a suspended license, was arrested.

The mayor warned about soaring temperatures following the storm, which reached the 90s. The city opened cooling centers for people without air conditioning.
