Monsoon moisture is returning to Southern California, bringing higher humidity, a chance for thunderstorms and another stretch of hotter weather for San Diego County, according to ABC 10News.

Forecasters said Sunday should stay mostly dry for the county, though isolated thunderstorms are possible over the mountains. The best chance for thunderstorms is expected Monday afternoon and evening, with some risk continuing into Tuesday for northern mountain and desert areas.

ABC 10News reported that another surge of monsoon moisture could arrive later in the week, which may raise thunderstorm chances again. The humidity is also expected to come with warmer temperatures after a brief weekend break from inland heat.

For Santee residents, the main impact is likely to be muggy afternoons, hotter inland conditions and changing skies over the nearby foothills and mountains. People planning hikes, youth sports or outdoor work should keep an eye on updated forecasts and be ready to move indoors if thunder develops.

Residents can monitor the National Weather Service and local forecasts for watches, warnings or changes as the moisture pattern develops.
