Titan weather forecast: Sunday was one of the wettest days of the decade in many parts of Southern California and it appears that Monday will follow suit, though Wednesday and beyond look dry. But don’t put away your umbrellas yet, Titans. There are still several months left before the typically drier spring and summer, with February averaging as the wettest month. Be careful on the roads this week and plan to arrive on campus well before your classes start so you can find a parking spot.
For millions of Californians, last winter was a letdown, as the strongest El Niño on record failed to deliver much-anticipated heavy rain to the Golden State. But this year, despite a weak La Niña that often brings below-average rainfall, the state has been awash with storm after storm. For the first time since 2010, Southern California has recorded a rainy season with above-average totals in many spots, including Downtown Los Angeles, the most often-cited location for assessing the Southland’s rain totals. Long Beach even recorded its wettest day ever on Sunday. With nearly three months remaining before the drier spring and summer arrives, there is reason for optimism that the season may make up for much of the rainfall deficit that has built up since the start of the decade.
Why it’s Raining
Most heavy rainfall in Southern California occurs as a result of atmospheric river events – when the jet stream, which powers weather patterns, sets up over the area and brings round after round of moisture-rich storms from the tropical Pacific. Over the past five years, such conditions did not occur due to a large ridge of high atmospheric pressure over the western U.S., which steered any needed rainfall to the north.
Since December, the ridge of high pressure has been largely absent, while a combination of storms from the tropical Pacific and weather systems from further north have converged on the state, not only bringing rain, but also heavy snow to the mountains. Continue reading
