On this day in…
2004: A large winter season storm pummeled Southern California. Not just daily, but monthly record rainfall was received in only one day across the region. The same happened again on 10.27. The monthly record rainfall was exceeded in only six hours in many locations of Orange County on this day. Totals for last two weeks of October were four to eight inches in lower elevations, and up to 14 inches at Lake Arrowhead. A storm wind of 39 mph was measured at Lindbergh Field from the south, the strongest October wind on record. 1.95 inches of rain fell in Riverside and 3.15 inches fell in Santa Ana, the greatest daily amounts on record for October. 3.5 inches of snow fell in Idyllwild, the greatest daily amount on record for October. Widespread flooding occurred. A bridge washed out near Wrightwood. One was killed in floodwaters near Lytle Creek. Many mountain roads were impassable with mud and rockslides. Railroad tracks washed out, derailing a train. The Santa Ana River flooded, putting horses neck-deep in flood waters in Norco and a rescue was made at a Chino golf course. Several funnel clouds were reported offshore from San Clemente.
