Here’s what a heat dome is, how it’s different from a heat wave and how hot it has to get for each region of Florida to issue a heat advisory.

Central Florida will feel another wave of intense heat on Wednesday. A heat advisory will be in effect from 12 p.m. to 7 p.m. for all of Central Florida. That is why WESH 2's First Warning Weather team has declared Impact Weather. Showers and storms will develop this afternoon and evening, with a 40% chance of coverage.

A heat advisory is in effect for all Central Florida counties on Wednesday. The heat index is expected to soar to between 105 and 110 degrees. Residents across Central Florida should prepare for another sweltering day,
