A fast-moving weather system left dry and windy conditions. The associated cold front will be accompanied by a band of clouds and followed by a day of gusty winds. Fire danger will increase in the hills with the dry, windy conditions. High pressure rebuilds into early next week.
***RED FLAG WARNING***
A dry system moving in from the north late tonight will produce a combination of gusty winds and low humidity values. Due to these factors and the recent long stretch of warm and dry conditions, a very elevated fire weather risk can be expected particularly for higher elevation locations.
The National Weather Service has issued a Red Flag Warning, which is in effect from 10 pm Friday through 10 am Sunday.
* AFFECTED AREA... Elevations above 1,000 feet, including the Santa Cruz Mountains, Diablo Range, Santa Lucia Mountains and Los Padres National Forest, mountains of San Benito County and interior Monterey County including Pinnacles National Park.
* WIND... Northerly winds of 15 to 30 mph with local gusts over 50 mph.
* HUMIDITY... Minimum humidity readings of 10 to 20% during the day. Nighttime maximum humidity readings will likely recover early in the night then drop of 25 to 35%.
* IMPACTS... Any fires that develop will likely spread rapidly. Outdoor burning is not recommended.
A Red Flag Warning means that critical fire weather conditions are either occurring now or will shortly. A combination of strong winds, low relative humidity, and warm temperatures can contribute to extreme fire behavior.
A dry system dropping down from the north late tonight will produce gusty northerly winds across higher elevation sections of our region.
The National Weather Service has issued a Wind Advisory, which is in effect from 10 pm Friday through 10 am Sunday.
* LOCATION: Elevations above 1,000 feet Monterey Bay Region, including the Santa Cruz Mountains, Diablo Range, Santa Lucia Mountains and Los Padres National Forest, mountains of San Benito County and interior Monterey County including Pinnacles National Park.
* WINDS: Northerly winds of 20 to 35 mph with local gusts over 50 mph.
A Wind Advisory means that winds of 35 mph are expected. Winds this strong can make driving difficult especially for high profile vehicles. Use extra caution.
Overnight: Windy/gusty conditions lasting through the night with gusts up to 50mph. Low temperatures will be in the 40s around the coast and mostly in the 30s for inland locations. High fire danger lasting until 10AM.
Sunday: Winds will slowly diminish under mostly sunny skies. Highs mainly in the 60s.
Monday: Mostly sunny and pleasant. Temperatures on the coast will be in the mid 60s and inland temperatures will be in the upper 60s.
Extended: High pressure will rebuild slightly during the early portion of the week with slight warming. Highs will generally stay a bit above normal with lows on the seasonable side. Another weather system will ride through in similar fashion on Wednesday, though this one has a better opportunity to tap some moisture. Wind could make fire danger elevated once again. Stay tuned!
