Description
As of October 1st, the rain calendar was reset and we are officially in the rainy season now through April. But La Nina is still in place for the third year in a row with its cooler sea surface temperatures, something that rarely happens.
While we are entering what’s considered our rainy season, San Diego is also potentially heading into its third year of the drought, the state of California is in its fourth year of the drought and it’s the third year in a row of La Nina.
"2020 to 2021, 21 – 22… two back-to-back years, water years that were about 60% of average,” said Alex Tardy a Meteorologist with NOAA National Weather Service, who added 2018 to 2019 was even drier.
"It was very dry. I think it was top five in terms of dry. We've been on a roller coaster,” added Tardy. "It's still the same magnitude, same intensity, and the reason that has some importance is it influences ocean temperatures and our weather, especially our rainy season."
Why that matters is that a La Nina can shift the storm pattern and leave much of California out of the storm track. And since most of our water comes from rain and snow in the Sierra Nevada and Rocky Mountains that can be a huge problem to the water supply.
