Weather Pattern Aims at San Diego

A strong winter weather pattern is taking shape, and San Diegans may already be seeing the first signs of it. Scientists say a powerful jet stream has formed between Hawaii and California, creating a pathway for moisture-rich storms tied to El Niño to reach the West Coast. The latest storm brought rain across San Diego County this weekend, and the National Weather Service says the region has already received about twice its normal October rainfall. La Jolla also set a record last week when a high tide reached just over 9 feet, the highest level recorded there in 102 years, causing minor flooding in places including Point Loma, Pacific Beach, Mission Beach and along Harbor Drive. Forecasters say more king tides are expected November 24th through 26th and again December 23rd through 25th, but it’s too early to know whether future storms and high tides will line up to cause broader flooding problems.
