More than 140 flights were delayed Monday at San Diego International Airport as a powerful storm swept through the region, bringing strong winds and heavy rainfall.

 

According to online flight-tracking data and the airport’s official website, at least 141 arrivals and departures experienced delays. At the same time, the National Weather Service issued a flood advisory for parts of San Diego County, along with a marine warning for winds ranging from 45 to 50 knots off the coast.

 

Forecasters said periods of rain, gusty winds and snowfall in the mountains are expected to continue throughout the week. There is also a slight chance of thunderstorms into early Tuesday, followed by lighter showers later in the day and strengthening west winds across mountain areas and desert slopes.

 

Heavier rain passing through the SD coasts/valleys now through the next hour, with areas 0.33" to 0.50"/hr rain rates, including downtown. Water running over and ponding on the roads, especially in low-lying areas, is very likely. If you must travel, take it very slow and easy! https://t.co/rL5jrryi0W

Meteorologists said another system bringing rain and lower-elevation mountain snow could move in from late Tuesday into Wednesday. Cooler and drier conditions are expected Thursday and Friday, though rain chances may increase again early next week.
