The National Hurricane Center is tracking four tropical waves. Sweltering temps continue for Florida, heat advisories are in effect..

A high pressure "heat dome" is sitting over the northern Gulf and spinning dry, hot air towards Florida. The hot air combined with high humidity is driving the heat indexes into the triple digits. While it feels hot outside, it has not reached the criteria this weekend for a heat advisory.

Another day of above-normal high temperatures and heat indices are on the way for the second half of the weekend across Central Florida. Highs will reach the low 90s near the coast and will approach the upper 90s for inland areas. Once we factor in the elevated humidity levels, feel-like temperatures will range from 107-111°.

Temperatures are only expected to worsen tomorrow. Monday could be the hottest day of the year, with much of the Orlando metro area reaching 98 or 99° as a high.

All of Florida will be under heat advisories Monday, July 21, as a heat dome spreads from the Ohio and Mississippi valleys. Here's what to know.
