Now, San Diego residents are cleaning up after the rains triggered mudslides, drenched streets and highways, delayed flights at Lindbergh Field and caused power outages.

The rains generated some notable rainfall records, including a one-day Palomar Mountain tally that exceeded the old maximum for all of October, the NWS reported.

Cloudbursts doused the eastern San Diego County peak with 6.26 inches of moisture over a 24-hour period starting at 4 p.m. Tuesday, soundly exceeding the previous single-day October record of 3.66 inches, set in 1974.

Until this week, the Palomar Observatory high for the entire month of October was 4.04 inches, also set 30 years ago, the NWS reported. Since Sunday, just over a foot of rain has fallen at the highland locale.

The rural town of Alpine also logged precipitation records, with 2.32 inches coming down in 24 hours. The previous daylong high mark there for any day in the month of October was 1.88 inches, occurring in 1974.

This month's Alpine total has reached 6.57 inches, surpassing the previous October maximum -- 3.94 inches, also in 1974.

Other rainfall records set locally this week:

Location	New Record	Old Record	Period Of Record
Lindbergh Field	0.95	0.59 1979	1850 to present
Ramona	1.50	1.03 1979	1974 to present
