Strong storms tore through Clay, Duval and St. Johns counties on Tuesday afternoon, knocking out power to 7,701 JEA customers just as an extreme heat warning pushed heat index values toward 115 degrees across Northeast Florida. The Mandarin neighborhood took the hardest hit, with 2,694 customers left in the dark, and a JEA troubleshooter was dispatched there as crews worked to restore service.
The outages amounted to roughly 1.41 percent of JEA's 546,281 total customers, according to News4JAX, which reported that JEA confirmed all 18 active outages were weather-related. Crews expected to have power back on in Mandarin by 5:54 p.m. Tuesday, per the same report. Customers whose outages had not already been logged were encouraged to report them, and JEA pointed residents toward its outage map for ongoing updates.
Storm Conditions Turned Dangerous Fast
The system that swept through Northeast Florida on Tuesday wasn't an ordinary summer squall. The National Weather Service had issued severe weather alerts for Duval, Clay and St. Johns counties, warning that afternoon thunderstorm cells could produce wind gusts between 40 and 55 mph along with frequent lightning and heavy downpours, according to the National Weather Service. Those storms developed rapidly along sea-breeze boundaries, a common trigger for fast-hitting convective weather in the region.
What made this round of outages especially risky was the timing. The storms hit while an active Extreme Heat Warning was in effect, with the weather service forecasting heat index values between 108 and 115 degrees across the area. Losing air conditioning during that kind of heat isn't just an inconvenience — it raises real health risks for elderly residents, young children, and anyone without a reliable way to cool down while crews work to get the lights back on.
Why Restoration Follows a Set Order
JEA is the largest municipal electric utility in Florida and the eighth-largest community-owned electric utility in the country, serving more than 540,000 customers across four Northeast Florida counties, according to background compiled by JEA. When outages hit, the utility doesn't fix neighborhoods at random. It follows what's known as a “Restoration 1-2-3” protocol, prioritizing public safety facilities like hospitals, water treatment plants and police stations, then repairing main distribution circuits serving about 2,500 customers, and finally addressing individual property connections.
That structure helps explain why a pocket like Mandarin, with nearly 2,700 customers affected, might see a targeted troubleshooter response while smaller, scattered outages wait their turn. JEA's broader infrastructure includes four utility power plants, 744 circuit miles of high-voltage transmission lines, and 200 megawatts of contracted nuclear power from Plant Vogtle in Georgia, according to filings with the Florida Public Service Commission.
Dark Traffic Lights Carry Legal Weight
Drivers navigating intersections with dead traffic signals during outages like this one aren't just dealing with an inconvenience — they're subject to a specific legal requirement. Under Florida Statute Section 316.1235, motorists approaching an intersection where signals are dark or inoperative due to a power outage must treat that intersection as a four-way stop, according to the Florida Senate. Failing to yield properly at a dark signal can result in a moving violation citation, making caution behind the wheel more than just common sense during localized blackouts.
It's also worth noting that not every Northeast Florida resident falls under JEA's restoration updates. Coastal communities including Jacksonville Beach, Neptune Beach, Ponte Vedra and Palm Valley get their electricity from Beaches Energy Services, an independent provider serving roughly 36,000 customers — a distinction Hoodline covered when a coastal wind storm knocked out power there earlier this year in an unrelated incident.
How This Compares to Bigger Storms
Tuesday's outage numbers are modest next to the region's worst-case scenarios. When Category 4 Hurricane Helene tore through in September 2024, it caused more than 121,000 JEA customer outages across the region, according to the Jax Daily Record, requiring a multi-day restoration effort. By comparison, Tuesday's 7,701 affected customers reflect the kind of localized disruption that regional electrical contractors say residential properties in the Jacksonville metro area can expect several times a year, with an estimated 8 to 15 outages annually tied to summer thunderstorms and coastal weather patterns.
For residents still waiting on service, JEA offers four ways to report an outage: texting “OUT” to 69532 through MyJEA, submitting a ticket online at jea.com/outage, calling (904) 665-6000, or using the utility's automated account portal. Anyone whose outage hasn't already shown up on the utility's map is encouraged to report it so crews can dispatch efficiently as restoration continues through the evening.
