Power outages are cascading through many parts of South Florida, with Florida Power & Light and others reporting blackouts in portions of Miami, Doral, Westchester, Pembroke Pines, Miramar and Boca Raton.

Many traffic lights are not working and nine accidents were reported in Miami-Dade County between 1:04 p.m. and 1:26 p.m. Police agencies were dispatching officers to as many intersections as possible.

The lights flickered off at several South Florida hospitals, which had to switch to generator power.

“We had a blip here and the generators kicked in immediately,” Jackson Memorial Hospital spokeswoman Lorraine Nelson said.

Mount Sinai Medical Center in Miami Beach and Baptist Hospital in Southwest Miami-Dade reported similar situations.

A spokeswoman for FPL said the company was investigating the extent and cause of the problem.

In one part of western Pembroke Pines, the outage began about 1:15 p.m., but service was restored within about 10 minutes.

The service failures came during an unusually warm February day in South Florida, with temperatures reaching near-record highs. At 1 p.m, Miami and West Palm Beach reported a reading of 84 degrees; it was 83 degrees in Fort Lauderdale.

Some air conditioning companies reported summer-like levels of service calls.
