SAN DIEGO (FOX 5/KUSI) — A monsoonal cluster of thunderstorms struck San Diego's mountain and desert areas on Sunday, dropping heavy rain while unleashing lashes of thunder and lightning.

The severe weather prompted several warnings throughout the afternoon and evening, including thunderstorm warnings, flash flood advisories, and special weather statements for hail and high wind. All advisories were lifted by 6 p.m. on Sunday.

At its peak, the cluster of thunderstorms was expected to drop between 0.25 to 0.75 inches of rain on eastern San Diego County communities per hour, according to forecasters with the National Weather Service. Here is a look at how much actually fell.

How much rain did San Diego get from Sunday's storms?

Higher elevation areas in San Diego's mountains and deserts were the primary recipients of the heavy rain dropped from Sunday's thunderstorms. Coastal communities and lower inland valley areas did not record any rainfall from the system.

As of 6 p.m. Sunday, Ranchita, an unincorporated community in San Diego County's desert, had recorded the most rainfall over a 12 hour period with 1.43 inches, according to NWS. Volcan Mountain came close behind with 1.39 inches.

To put that in perspective, both of these areas received about 5% of their annual average on Sunday, as each get about 30 inches of rain every year.

Pine Hills and Julian also received over an inch of rain during Sunday's thunderstorm, NWS said — the communities recorded 1.27 inches and 1.24 inches respectively.

Valley areas to the west of San Diego's mountains like Alpine and Ramona, who were on the outskirts of the thunderstorm system, recorded a small amount of rain Sunday. According to NWS, Alpine received the most out of these areas with 0.12 inches.

Below are 12-hour rainfall totals reported by NWS as of 6 p.m. Sunday.

As far as lightning strikes go, NWS reports a total of 8,953 were recorded over the weekend, including 713 that were cloud-to-ground. Hail was also reported in several of the communities hit by the storms, including Julian and Pine Valley.

Are more thunderstorms coming?

According to NWS, the chances of thunderstorm activity will be lower compared to Sunday, although models indicate there is still a strong likelihood additional storms could form over eastern San Diego County.

"With just enough moisture left in place, we will see one more day for a notable chance of thunderstorms," forecasters said Monday. As of 7:30 a.m., no severe weather advisories have been issued.

Forecasters estimate probability for precipitation is roughly 10 to 25% in the county's mountain and desert areas, while Riverside and San Bernardino County's desert areas have thunderstorm chances of up to 30%.

Through the remainder of the week, conditions are anticipated to return to seasonal weather as a trough to the north brings in cool, dry air. For coastal areas, this trough will also deepen the marine layer throughout the week.
