IS A WARM CUP

July 18, 2025 3:30 pm

Southern California Overview:

  • Showers and thunderstorms will continue across the mountains and deserts through this evening as pesky marine layer clouds hover over parts of the coast. Monsoonal activity will decrease on Saturday with a minor chance of storms being focused in the mountainous regions. By Sunday into the middle of next week, a troughing pattern will take hold over the region, leading to dry weather with temperatures near to below average with marine layer clouds closer to the coast each morning. This pattern may linger into later next week as well.

Your 5-Day Forecast at a Glance

On this day – 7.18.2015

Moisture from Hurricane Dolores, along with monsoon moisture resulted in showers and thunderstorms over most of Southern California on this day through 7/19. Rainfall ranged from 0.5 to 4 inches, including a record 1.71 inches at San Diego on this day. This was unprecedented July rainfall: record single-day and July monthly total. These two days recorded two of the three wettest July days on the San Diego record. The San Diego River at Fashion Valley had two crests above monitor stage, 7.7 feet on this day and 8.8 feet on 7/19. A debris flow hit the burn scar of Silverado Canyon on 7/19 as well as flash floods in Moreno Valley, Perris, and La Mesa. A wet microburst struck San Diego’s Tierrasanta on this day, causing wind damage, and a haboob caused wind damage in the Anza Borrego Park and also in Palm Desert. On this day the rain caused the first rain-out of a Los Angeles Angels baseball game since 1995, and a rare 2-hour rain delay at the San Diego Padres baseball game. Over 2000 lightning strikes were reported on this day, some starting small brush fires. Isolated intense thunderstorms developed across far southern Imperial County on this day. Large hail of 1.25 inches was observed on this day in the town of Heber, just to the south of El Centro, but no hail damage was reported.
