JACKSONVILLE, Fla. – Afternoon high temperatures are expected to climb into the mid to upper 90s by mid to late afternoon.
Peak heat index values are forecast to reach 108 to 112 degrees across nearly the entire region. That level of heat stress qualifies as dangerous for most people, especially those spending time outdoors.
A Heat Advisory is in effect beginning as early as 11 a.m. Sunday and running through 8 p.m. Sunday evening. The advisory will be most impactful in areas that stay dry throughout the day, as any rainfall could offer brief but temporary relief from the most intense heat.
Storms possible
Some storm activity is expected to develop though that activity is forecast to fall apart before midnight Sunday night. Following the storms, leftover cloud cover will slowly clear through the overnight hours and into the early morning hours Monday.
Unfortunately, overnight relief will be hard to come by. Low temperatures Monday morning are only expected to drop to the 75 to 80 degree range.
Stay safe in extreme heat
Health officials consistently warn that extreme heat is one of the deadliest weather hazards. Residents are urged to:
- Limit outdoor activity during the hottest parts of the day, typically between 10 a.m. and 6 p.m.
- Stay hydrated by drinking water frequently, even if you don’t feel thirsty.
- Check on neighbors, the elderly, young children and pets.
- Find air-conditioned spaces such as libraries, malls or cooling centers if your home does not have air conditioning.
The Heat Advisory remains in place through 8 p.m. Sunday.
