A quick-developing thunderstorm was heading toward Burbank this afternoon, according to the National Weather Service, with a brief heavy rain expected and possible flooding.
"We have a cell just north of Burbank right now heading south towards the city, and we don't have any lightning with that cell yet, but it definitely looks like a heavier shower," NWS spokesperson Robbie Munroe told KPCC.
Isolated to scattered showers, with isolated thunderstorms, were expected to last until just before midnight, Munroe said. Other parts of the area are seeing rain as well.
"What we've seen with some of the other cells so far today is heavier rain rates, upwards of an inch or even more per hour, with some of the heaviest cells, which has led to reports of minor flooding, or urban flooding, for portions of southeast L.A. County, as well over towards the Simi Valley area," Munroe said.
The storm is expected to continue east before being replaced with a ridge from the west, which will lead to a "fairly significant warming trend" from Wednesday into the weekend, Monroe said — with some areas hitting more than 100 degrees. There's also a possible Santa Ana wind event this weekend offshore.
