The annual monsoon season, typically between June and September, often brings landslides, flash floods and waterborne diseases.

The National Weather Service has canceled the flash flood warning for much of Southern California.

The agency’s Weather Prediction Center says large swaths of Southern California have a “moderate flash flood” risk on Saturday, defined as at least a 40% chance of intense rainfall that could lead to flash flooding.

Local officials have warned of flash floods, landslides and river overflows.

Thailand is also bracing for the storm's impact, with local officials warning of possible flash floods, landslides and river overflows caused by Kalmaegi.
