A Monday storm that dumped much-needed rain and snow across San Diego County was expected to peter out overnight into Tuesday, according to the National Weather Service in San Diego.
Monday’s storm brought the county’s first significant traces of precipitation since the first week of November, when a North Pacific storm dropped several inches of snow in the mountains and some rain off to the west.
Earlier this year, the Center for Western Weather and Water Extremes launched a new sub-seasonal to seasonal forecast product to better predict the influence atmospheric rivers will have on the Western United States. Better and more accurate forecasting tools for atmospheric rivers are critical for a number of community uses, including water management, agriculture, insurance and commodities trading, to name a few.
The demand for better atmospheric forecasting tools has facilitated the development of the new S2S forecasting products launched by CW3E this year.
More than a month and a half into this year’s rainy season and significant precipitation was finally falling on Tuesday in Northern California. The state could use it in more ways than one.
In some places, more than an inch of precipitation fell Friday in Northern California while other places, including Sacramento, saw only a fraction of that. Whatever came down in the first rains of the season were a mere drop in the bucket.
San Diego researchers are getting a better understanding of the storm systems that bring the region most of its rain and they are getting that information the old fashion way — from weather balloons. Last March, gray rain-filled skies seemed to dip into the ocean as a storm moved across the region.
It won’t take much, and the Pass Area as we know it may look dramatically different come wet weather this fall and winter. That’s according to public safety officials from various Riverside County agencies who are working to get the word out about the danger of “flood after fire.”
Meteorologist Emily Heller says the weather lately reminds her of what Northern California saw in 2018 just before the Camp Fire set the town of Paradise ablaze. For weeks, there was no rain, excessive heat, and dry winds.
As Americans hunker down to weather the pandemic this winter at home, nearly every facet of life will remain upended to safeguard against the coronavirus. Millions are working from home and learning remotely and even holiday gatherings will look a lot different this year. Staying closer to home may mean fewer weather worries for commutes and disruptions to daily activities, but AccuWeather has you covered on what you can expect weather-wise as we navigate uncertain times.
The autumn equinox was at 6:30 a.m. PDT on Tuesday, meaning there are nearly equal periods of daylight and darkness. From now until the winter solstice in December, days will gradually get shorter and nights will get longer in the Northern Hemisphere.
Hurricane Genevieve fizzled after hammering Mexico’s Baja Peninsula, but its remnant moisture and spin may boost thunderstorms in the Desert Southwest and fire-ravaged California through Monday.
Genevieve rapidly intensified to a Category 4 hurricane Tuesday, then grazed Mexico’s southern Baja California Peninsula as a weaker hurricane with flooding rain, high winds and high surf.
After that, as most hurricanes in this part of the eastern Pacific do when they move farther northwest over cooler water and more stable air, Genevieve fizzled rapidly into a remnant low west of the Baja Peninsula.
