Elsewhere, season totals fell short of 10 inches, and were generally within 50 to 80 percent of averages. In East Highland, an exceptionally high season total of 29.20 inches was reported - due to unusually persistent, heavy rainfall during December (courtesy of Peter Michas). Simi Valley, like much of the Los Angeles Basin south and east of it, benefited greatly from one particular storm in late December - which badly missed the rest of the region. However, Anza's season total is not considered to be accurate due to overreporting rainfall in December, and that season total is likely around 3 inches higher than it should be (roughly 9 inches). Season totals exceeded 12 inches at two WeatherCurrents stations, in Simi Valley and Anza. Much of the region last saw measurable precipitation in April. A small number of mostly weak systems managed to pad season totals in February and March, with one thunderstorm-laden event in late March being somewhat notable. November was kept dry by a persistent blocking pattern throughout the entire month, and following the region's wet December, a stubborn dry pattern once again gripped much of the entire state in January - and for most of the remainder of the water year. Outside of those two months, remained a largely inactive, quiet rainy season. October 2021 was the only other month of the season with even semi-consistent storm patterns. For virtually all locations across the region, December 2021 was the wettest period of the winter, where a significant portion of the season's total rainfall fell alone. Most WeatherCurrents stations with accurate season totals finished the 2021-2022 water year with less than 10 inches of rainfall - however, in the majority of locations, seasonal rainfall for 2021-2022 still exceeded that of the previous year, 2020-2021. This story originally appeared in Los Angeles Times.California witnessed another La Nina winter, for the second time in a row during the 2021-2022 water year, with the resultant seasonal rainfall for much of the region once again ending below-average. 'Do not go into or even approach rivers in Yosemite,' the park said in a statement on Twitter. But as the park fully opened Monday, park officials warned visitors the rivers remained 'extremely dangerous.' Yosemite National Park closed over the weekend due to flooding concerns from a high Merced River, but park officials said the river did not rise as high as expected, partially reopening the park Sunday. The cool temperatures mean there's less of a concern for rapid snowmelt across the state - and subsequent flooding - but rivers are still running very high, fast and cold, officials warned.

“Anyone expecting to travel through that area should be up to date on the weather,' Kittell said.įorecasts show temperatures won't vary too much through Friday, but by the weekend, the region should start to slowly be drier and warmer.

He said the Grapevine shouldn't get too bad, but delays are possible. “All the snow will stay up in the mountains, but most mountain areas should expect an inch or two,' Kittell said, with as much as eight inches possible in the highest elevations. Snow levels will drop by Tuesday to around 4,000 to 5,000 feet elevation, with a few inches of accumulation expected. “With those thunderstorms, we could see small hail, gusty winds.' “We are expecting thunderstorms,” Kittell said, with the greatest likelihood late Wednesday into Thursday. This week's weather will also bring a chance for thunderstorms, and snow is likely at elevations around 5,000 feet - including the Tejon Pass. 'It’s rare in that we don’t get rain every May, but it’s not unprecedented,' he said.

Los Angeles County gets a May rainstorm every three to five years that can total around half an inch, but it's not expected each year, Kittell said. Forecasters noted that San Diego typically averages only three days of measurable rainfall for the whole month of May, a mark the region will easily reach just this week. San Bernardino County's mountains could also see around a half-inch of rainfall this week, as well as many regions across Riverside, Orange and San Diego counties, where the heaviest rainfall is expected Wednesday and Thursday, according to the National Weather Service. Rain amounts between 1/3-1' and 4-8' snow above 5,000'.

We are still looking at a big change in the weather this week, with a storm system bringing rain & mountain snow Tue-Thu.
