    An upper-level low spinning into the region brought thunderstorms and flooding to parts of Southern California, including the Antelope Valley, forecasters said.

    A flash flood watch was in effect from 2 p.m. through Friday evening in the Antelope Valley north of Los Angeles and the San Gabriels in Los Angeles County.

    "We have an interesting weather day," said NBC4 forecaster Crystal Egger. "We have this upper-level low that will trigger the instability. Most of the thunderstorms will be over the mountains and across the high desert with a few rolling into the valley."

    Rainfall was concentrated over a small area, increasing the potential for flash flooding.

    A flash flood watch means that conditions may develop that lead to flash flooding. The watch indicates the potential for dangerous and sudden pooling of water and swift-moving water.
