San Diego Weather Alert: Tropical Storm Mario to Unleash Showers!
San Diego residents, brace yourselves! After a scorching start to the week, a shift in weather patterns is on the horizon. While today saw above-normal temperatures, especially inland and in the mountains, the real story unfolds later this week with the potential arrival of Tropical Cyclone Mario's moisture.
Heatwave Before the Storm
Tuesday is expected to be the peak of the heatwave, with temperatures soaring 4 to 8 degrees above normal across most of the region, excluding the desert. Prepare for highs in the 90s inland and sweltering conditions in the mountains.
Tropical Moisture Incoming
The atmosphere will become increasingly humid starting Wednesday, creating a tropical feel throughout San Diego County. This humidity is a prelude to the main event: the arrival of moisture from Tropical Cyclone Mario. This influx will increase the chance of showers and thunderstorms across the county, potentially becoming widespread in some areas.
Timing and Potential Impacts
The peak of the storm activity is anticipated from Wednesday night into Thursday. Showers are expected to gradually taper off Thursday night, but isolated showers and thunderstorms may persist in the mountains and deserts into Friday. A slight chance of storms could even linger in these areas on Saturday before the moisture finally dissipates by Sunday.
Possible Hazards
Any storms that develop could bring brief, heavy rainfall, small hail, lightning, and the potential for localized flash flooding, particularly in the mountains and deserts. Residents in these areas should be especially vigilant and monitor weather updates closely.

Remember to stay hydrated and take precautions during the heatwave. And as the humidity rises, be prepared for potential showers and thunderstorms later in the week. The end of the muggy weather is in sight, with more comfortable humidity levels expected by Monday, just in time for the Autumnal Equinox at 11:19 am on September 22nd.
