A tornado watch is in effect for most of Central Florida through 8 p.m., according to the National Weather Service.

The alert is for more than a dozen Florida counties, including Orange, Seminole, Volusia and Lake. A tornado watch is issued when weather conditions are favorable for the development of tornadoes in and close to the watch area.

The weather service also warned of strong storms possible in the area this afternoon and into the evening. An approaching line of showers and storms is expected to impact Lake and Volusia counties starting between 5 and 8 p.m. It is expected to hit the Kissimmee and Orlando areas between 9 p.m. and midnight.

The weather service said an isolated tornado could occur, but the main threat will be from lightning and wind gusts. Large hail also will be possible.
