Summer months are usually dry across California, and the first half of September was no different, with most of California leaving — including the cities of Sacramento, which saw an all-time high of 116 degrees on September 6, and neighboring Davis. Dry and bake. The notable exception to the dry conditions was the heavy tropical rainfall from Remnants of Hurricane Kai In the far south of the state. In the past few days, unusual September rains have fallen from Santa Barbara across the California/Oregon border.
At Davis University Airport, 1.7 inches of rain have been recorded in the past 24 hours. While this type of rain may not be unusual in many locations in the United States, it is out of the ordinary in the Davis region, which sees on average less than a tenth of an inch of rain in September.
“There have been some minor flooding, road flooding and so on in severe thunderstorms, and there have been reports of minor ash flows and debris flows and burning scar areas,” Chris Hintz, a meteorologist with the National Weather Service in Sacramento, told The Washington Post. .
On the UC Davis subtitle, students shared photos of the subsequent rainfall and flooding, with swimming students In a flooded tunnel. photos too Showed slight flooding In the school’s student union building.
A photo posted by the city’s Twitter account showed minor flooding in a local tunnel, as the city asked drivers to take alternate routes in and out of the city.

The flash flood watches have been lifted in search of a burn scar mosquito fire — California’s biggest fire of the year — which as of Tuesday morning was only 39 percent contained, after burning 76,000 acres northeast of Sacramento.
When heavy rains fall on burn scars, streams of ash and debris can sometimes be released, especially in steeper terrain, which can lead to dangerous firefighting. Wet weather brings some advantages to firefighters as well, as higher temperatures and higher humidity help fight a fire.
“Fire activity has slowed, but firefighters have not,” the US Forest Service wrote in its report. Tuesday morning update. “While rain presents a different set of challenges to fire suppression efforts, crews continue to work, taking advantage of a lull in fire activity to secure the fire perimeter and increase containment before warm, dry weather returns.”
Unfortunately, rainfall in the region will not be enough to make a significant impact in the severe to severe drought conditions that persist across the state.
“This little one isn’t going to make much of a difference to the overall drought picture, but the fact that we’re starting to see big storms like this is favorable,” Hintz said.
After the low pressure regime passes through the region, medium to long-term forecasts for Northern California show a return to hot, dry conditions, with the latest US Model Operations (GFS) showing the possibility of several days with highs in the 1990s, or even topping 100 degrees, in California’s Central Valley By late next week.
