Monsoon weather brings possible thunderstorms, flood watch in San Diego mountains, deserts – NBC 7 San Diego

A monsoon weather pattern was expected to continue over San Diego County into next week, resulting in a daily risk of thunderstorms over the mountains and deserts, the National Weather Service said Saturday.

Humidity levels could be at their highest on Saturday, with flash flooding possible over the mountains and deserts, weather forecasters said. A flood watch was issued for the deserts and mountains of San Diego County through Saturday night.

A heavy downpour hit the National Weather Service’s office in Rancho Bernardo Saturday, where about a third of an inch fell in less than an hour.

Slight daily temperature changes have been predicted for the next few days, while humidity will remain high.

High temperatures along the coast on Saturday were forecast to be in the low 80s, with overnight lows in the upper 60s. Highs in the western valleys were expected around 90 and mid 90s near the foothills with overnight lows around 70. Mountain highs were expected with overnight lows around 70 and highs in the lower 90’s. Deserts were forecast at 93 to 103 with overnight lows in the upper 70’s.

“Meanwhile, we’re going to have similar weather for the next five days or so, albeit not quite as hot,” meteorologists said.
