UPDATE, Sunday, 7:30 a.m.

The National Weather Service has issued a flood watch for Carson City.

The watch begins at noon Sunday and continues through late Monday, the NWS said in a statement at weather.gov.

Widespread rains, cooler conditions and an increased risk of flooding are the result of Hurricane Hilary.

“Hilary in the eastern Pacific is forecast to make landfall (Sunday) near the northwestern portion of Baja California,” the NWS said. “While this system will rapidly weaken by the time it arrives in Nevada, significant amounts of moisture will bring periods of heavy rainfall to the region (Sunday) afternoon through Monday. The greatest threat for flooding is across the Basin & Range and the eastern Sierra. However, isolated flooding cannot be ruled out elsewhere across western Nevada and northeast California.

“Abundant cloud cover and rainfall will keep afternoon high temperatures 10 to 20 degrees below normal today through Tuesday, with Monday likely being the coolest day.”

UPDATE, Saturday 6:45 a.m.

The National Weather Service said in a statement Saturday morning that showers and thunderstorms will develop Saturday afternoon and evening in Carson City. These storms will be capable of gusts in excess of 45 mph, localized heavy rainfall and small hail.

“Major Hurricane Hilary in the eastern Pacific is forecast to make landfall Sunday along northern Baja of California or extreme southern coastal California,” the release continued. “While this system will rapidly weaken into a remnant low by the time it reaches Nevada, significant amounts of moisture will bring periods of heavy rainfall to the region Sunday afternoon through Monday. The greatest threat for flooding is across the Basin & Range and the eastern Sierra. However, isolated flooding cannot be ruled out elsewhere across western Nevada and northeast California.”

INITIAL STORY

Thunderstorms and rain showers are expected to the Carson City region through the weekend due to moisture rotating across California into the Sierra and later from remnants of Hurricane Hilary pushing up from the south.

“Daily showers and thunderstorms are anticipated into the weekend with localized flash flooding possible,” the National Weather Service said Friday. “A significant influx of tropical moisture from Hurricane Hilary will promote widespread showers and storms Saturday night through Tuesday morning, increasing flooding potential, especially for areas south of U.S. 50.”

A flood watch is in effect from Sunday afternoon to late Monday night for Mono County in California and Mineral and southern Lyon counties in Nevada. A flood watch for the Las Vegas area is in effect from Saturday morning to Monday afternoon.

Parts of western Nevada could see significant rainfall over the weekend.

“Remnant tropical moisture, from what is currently Hurricane Hilary, will surge into the southwest U.S. Sunday through Tuesday,” said the NWS. “How this interacts with a trough off the west coast will have varying implications on the forecast for the eastern Sierra and western Nevada. Keep in mind, this will not be a hurricane when it makes landfall.”

With showers, temperatures will drop to the 70s — 10 to 20 degrees below normal.

“Much of the region will receive at least a half inch of rain over the multi-day period,” said the NWS. “The best chances for higher liquid totals will be south of U.S. 50, where there is a 30 to 50 percent chance for at least 2 inches of rainfall.”

The NWS advised there is a level of uncertainty in the forecasts because “changes in the track of the hurricane remnants will bring differing impacts.”
