Meanwhile, a Flood Watch continues to remain in effect for the Mother Lode, through late tonight.

Isolated thunderstorms with heavy rain may occur this afternoon.

Flooding may occur in poor drainage and urban areas. Low-water crossings may be flooded. Storm drains and ditches may become clogged with debris.

You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
