Jacksonville is taking a break from the heat waves and cooling off with showers. A low-pressure system just off the coast of Florida is expected to bring torrential downpours and the potential for flash flooding across the state for the next few days, according to a July 23 update from the National Hurricane Center.
The NHC said there is very little chance the system, currently just off the coast around Jacksonville Beach and St. Augustine, will develop into a tropical depression before it hits the state. But the system will drench North Florida as it tracks across into the Gulf where there is a small chance it could strengthen before it threatens Louisiana and Texas through the weekend.
