Showers and thunderstorms brought flooding in parts of San Diego County Sunday and could continue into the work week, the National Weather Service said.

The chance of rain continue on Monday but with more isolated activity and less intensity as the atmosphere continues to dry out.

“Chances for showers and thunderstorms continue Monday afternoon,” the weather service said. “It will continue partly cloudy and rather muggy,  but not oppressively hot.”

Highs on Monday were expected to be in the upper 70s near the coast, lower 80s inland, mid 80s in the valleys, upper 70s in the mountains, and mid 90s in the deserts.

Campo received a record 0.88 inches of rain on Sunday, breaking the old mark of 0.44 inches set on Sept. 11 seven years ago. Other rainfall amounts as of 4:15 p.m. were

  • Echo Dell in Mission Trails Regional Park — .88 inches
  • Descanso — .83 inches
  • Ramona — .67 inches
  • Alpine — .61 inches
  • Goose Valley — .59 inches
  • Cactus City — .59 inches
  • Palomar — .26 inches

The remnants of Tropical Storm Kay were about 300 miles southwest of San Diego and continuing to impact local weather, though rain activity was expected to taper off during the week.

“Chances of showers and thunderstorms continue to decrease Tuesday through the end of the week,” the weather service said, forecasting temperatures “slightly below or near average.”

A deeper marine layer was predicted to allow for night and morning low clouds and fog into portions of the valleys through Thursday.
