Jacksonville, Florida – People in Jacksonville should prepare for extreme heat and heavy rains through Monday. The National Weather Service has issued a heat advisory with dangerous heat index values near 110°F, along with the possibility of strong afternoon thunderstorms each day.
If you’re planning to go outdoors this weekend, be careful. The combination of very hot weather and sudden rain could affect daily life, travel, and events across Duval, Clay, and St. Johns counties.
Stay Safe in the Heat: Friday to Monday
On Friday, temperatures will reach 98°F, but it will feel more like 109°F because of the humidity. Afternoon thunderstorms may arrive after 2 p.m., with chances of gusty winds and sudden heavy showers.
These storms may cool things down for a bit but could also cause local flooding and traffic issues on roads like I-95 and Philips Highway.
Saturday looks worse, with the heat index at 106°F and a high 80% chance of storms after 11 a.m. Outdoor events and weekend plans could face delays, especially in Jacksonville, Orange Park, and St. Augustine.
Sunday and Monday: Storms Take Over
On Sunday, rain becomes more widespread, with a 90% chance of thunderstorms. Expect cooler temperatures around 90°F, but flooded roads and scattered power cuts could cause problems.
Monday and Tuesday continue this pattern, with heavy showers, a high chance of rain, and heat staying in the low 90s.
If you’re stepping out, carry water, avoid long hours in the sun, and keep your phone charged in case of power cuts. Use fans or air conditioning indoors, and keep an eye on local weather alerts.
