Rare Summer Storm Set LA Rainfall Records – NBC Los Angeles


It wasn’t much, but Wednesday’s rainfall set records in parts of Los Angeles County.

The rare early summer thunderstorms had no high bar to set in an area where rain during the summer is highly unusual.

Here are some of the precipitation records set on Wednesday.

  • Long Beach Airport: 0.11 inches of rain broke the old track record set in 1967.
  • Lancaster: 0.51 inches of rain broke the old record of zero inches.
  • Palmdale Airport: 0.3 inches of rain broke the previous record of zero inches.

Thursday should be clear with above normal temperatures. Thunderstorms are possible in the mountains of southern California.

Most of Southern California remains in severe to extreme drought after a dismal winter with little precipitation. Statewide, nearly 60% of California is experiencing extreme drought, the second most severe category in the weekly US Drought Monitor report. Ninety-seven percent of the state is in severe drought.

The worst drought conditions are in the Central Valley north of Los Angeles.

California has spent most of the past 15 years in drought conditions. The current three-year drought included one of the driest late winters on record. The state’s normal rainy season runs from late fall to late winter, but dismal rainfall has left about 95% of California in severe early spring drought with months hot, dry summers ahead.

Much of California’s water comes from snowmelt in the Sierra Nevada mountains. In an ideal scenario, storms cover the mountains with snow during the winter, forming the natural reservoir. This snow then melts in late spring and early summer, replenishing the state’s water system.

Snowfall was well below normal this year.
