A storm system is expected to bring moderate to locally heavy rain to the region, with a slight chance of thunderstorms Wednesday.
The National Weather Service (NWS) said mostly dry and cool weather is expected Thursday into early Friday. Forecasters predict another, weaker storm may bring some showers to the region late Friday through early Sunday, with dry, warmer weather returning next week.
In their forecast, NWS said their models are having trouble settling on where heavy rain will fall.
“Yesterday’s focus was over the coastal waters and eastern LA County but today that has shifted west to SB County where the most unstable air will be during the late morning and early afternoon hours,” said the forecast. “Overall rain amounts still look on track as mentioned below but there will be pockets of heavier rain as with the last system that caused isolated locations to have considerably more than the average.”
Forecasters are predicting total rainfall of 0.75 to 1.5 inches and up to 2 to 3 inches possible across some areas. Snow is predicted to fall between 6,500 and 7,500 feet.
“Winter weather advisories may be needed, since there is a chance that snowfall totals could reach 3-7 or 4-8 inches at elevations above 7,000 feet. Rainfall rates could exceed one half inch per hour, which could cause minor mud and debris flow for recent burn areas,” said the forecast. “Heavy rain and snow melt could cause flooding concerns in the mountains.”
The Los Angeles County Health Office extended a Cold Weather Alert due to the National Weather Service’s forecast for low temperatures. Wind chill temperatures are expected to be below 32 degrees Fahrenheit in some mountain areas and the Antelope Valley.
“Children, the elderly, and people with disabilities or special medical needs are especially vulnerable during cold weather. Extra precaution should be taken to ensure they don’t get too cold when they are outside,” said Muntu Davis, MD, MPH, Los Angeles County Health Officer. “There are places where people can go to stay warm, such as shelters or other public facilities. We also want to remind people not to use stoves, barbecues or ovens to heat their homes due to the risk of carbon monoxide poisoning.”
