Jacksonville is currently under a heat advisory as heightened temperatures and humidity levels are forecasted to affect the area through this weekend. The advisory was issued on August 1 and is expected to impact much of Florida, with Jacksonville experiencing peak heat index values between 105 and 112 degrees Fahrenheit.
Daily high temperatures in Jacksonville will range from 94 to 99 degrees Fahrenheit. This increase in heat comes alongside a slight chance (20%) of scattered showers and thunderstorms after 2 p.m. today. Tonight, the probability of storms rises to 30%, mainly before 9 p.m., while temperatures will drop to around 78 degrees Fahrenheit under mostly cloudy skies. Winds are anticipated to decrease to 5–7 mph.
The heat advisory is likely to continue throughout the weekend, with high temperatures projected to reach up to 96 degrees Fahrenheit. The heat index may push values up to 108 degrees, indicating a significant risk for heat-related illness. Residents and visitors are urged to take precautions outdoors during this extreme heat.
Alongside the heat, a “slight risk” of excessive rainfall is forecasted for areas north of I-10, adding another layer of concern for residents. Morning showers are expected on Sunday, with widespread thunderstorms likely after 11 a.m.. The chance of rain on Sunday is projected at 90%, with expected highs around 90 degrees Fahrenheit.
Rainfall totals for this weekend are anticipated to range from 2-4 inches, and localized amounts of up to 6 inches are possible, particularly due to heavy downpours. This has created a weekend flood risk, especially for residents in Southeast Georgia and Northeast Florida near the I-10 corridor. The National Weather Service emphasizes the necessity for vigilance in light of the heat and impending storms.
In addition to the heat advisory and potential rain concerns, Jacksonville is also facing increased rip current risks at local beaches due to tropical systems being monitored in the Atlantic. While no significant tropical development is expected over the next seven days, weather authorities will continue to provide updates on any changes to the situation.
With the potential for hazardous weather conditions both from extreme heat and rainfall, residents are encouraged to stay informed and cautious. Those experiencing adverse conditions can share their weather-related photos and videos with local news sources to contribute to community awareness.
