(CNN) — Two storms, including another long-lasting atmospheric river event, will drench much of California this weekend and well into next week, raising the risk of flooding and landslides.

The state is still recovering from a particularly potent storm that brought record-breaking rain and hundreds of mudslides to Los Angeles and other parts of Southern California in early February.

The two storms aren’t forecast to be as devastating as early February’s, but the repeated rounds of rain and the slow-moving nature of the second storm will bring a significant threat for flooding.

As a result, more than 27 million people are under flood watches stretching from Northern California south to parts of the Los Angeles area.

The first storm is expected to be weaker than the second, but “will act as a primer, increasing soil moisture and causing the streams and rivers to rise before the heavier rain on Sunday” from the second storm, the National Weather Service said. It will march into the Northern California coast early morning Saturday and spend the rest of the day soaking the region with 1 to 2 inches of moderate rainfall. Only light rain is expected in the Central Coast and Southern California.
