It’s going to be a wet Halloween weekend as two back-to-back storms blow through the area, dropping heavy rain and mountain snow, Reno forecasters said.
“The first storm starts now and into Friday,” meteorologist Scott McGuire, of the National Weather Service, said Thursday afternoon.
The amount of measurable water from the storms will be near or above record values for October for the Sierra and western Nevada region, forecasters said.
The heavy rain is a big concern for rock and mudslides near recent burn areas, forecasters said.
Residents near the Emerald Fire, Little Valley Fire or Marina Fire burn scars should be prepared. A rise in rivers are also likely, but forecasters don’t expect any flooding. McGuire said some residents could see some localized flooding on Friday, mostly likely because of clogged storm drains.
Snow is expected to cover mountains peaks at 9,500 to 10,000 feet in elevation, McGuire said. The Tioga and Sonora passes could be hit with wet, heavy snow.
“It will be moderate to heavy rain in the Sierra, and then we’ll get some decent amount of rain here too,” he said.
The heavy rainfall could cause travel delays, “especially for those crossing the Sierra,” forecasters said. “The peak period for heaviest rainfall looks to be early Friday morning.”
Water could pond on roadways, and that means drivers should be prepared for a slower commute Friday morning.
Forecasters expect a small break Friday into Saturday with some lingering showers.
“The second (storm) comes at the heels of the first one,” McGuire said Thursday.
That means more colder rain and snow showers are expected to fall over the region by Saturday night into Sunday evening, he said.
Snow levels could start at 8,500 feet in elevation and then move down to 6,500 feet by late Sunday afternoon and evening.
“If folks need to travel, the best window will be Friday night into Saturday,” McGuire said.
Clouds could linger over the Reno-area by Monday as the storm moves out of the area. Temperatures could reach into the high 60s and dip down to a low of 38 degrees.
McGuire said a third storm system could hit the region next week with more rainfall and high elevation snow.
“It might not hit the Reno area, but the potential is still there for the storm to move right over us,” McGuire said.
Winds were expected to gust at 80 to 90 mph in the mountains over the weekend. The valley areas could see gusts up to 30 to 40 mph, McGuire said.
“Winds are always a fire concern, but we’re moving out of the traditional wildfire season,” he said.
