A flash flood watch remained in effect Thursday for Yosemite and portions of central California.

The National Weather Service said heavy rain totaling up to 4 inches in some areas could lead to excessive runoff, rising water levels on rivers and streams and flash floods.

Mud, rock and debris slides were possible, especially in the burn scar areas left by the Ferguson, Railroad and Pier fires.

Besides Yosemite, the flash food watch covered Mariposa, Madera, and Fresno County foothills; the Sierra Nevada from Yosemite to Kings Canyon; and Tulare County foothills and mountains.

Yosemite roads that were closed Wednesday night ahead of the winter storm because of the potential for mudslides and debris slides reopened Thursday. They include:

  • Wawona Road, El Portal Road from El Portal to Yosemite Valley, and the Big Oak Flat Road..
  • Highway 140 from Midpines to El Portal west of the park.

Most of the park received rain during the Wednesday's storm, but higher elevations — above 7,000 feet — saw significant snow accumulations.
