LOS ANGELES — Moisture from former Hurricane Blanca is streaming over Southern California, bringing light showers.
The National Weather Service says the subtropical moisture is being pulled into the region by a low-pressure system approaching the area Tuesday.
Instability in the atmosphere could bring afternoon thunderstorms.
Forecasters say cloud cover will keep temperatures lower than Monday, when triple-digit heat arrived, but the added humidity may make it feel worse.
Hurricane Blanca formed in the Pacific Ocean off southern Mexico and moved northwestward. It later was downgraded to a tropical storm and then a depression.
