WINDY TODAY THROUGH THIS EVENING…STRONGEST WINDS OVER THE MOUNTAINS AND DESERTS***

A trough will move through the state today with showers and a few thunderstorms continuing across Central California through this evening. It will be very windy from the west across the mountains and deserts today with the strongest winds along both the Sierra Crest and over the spine of the Cleveland National Forest, where sustained winds will be in the 20-45 mph range. Elsewhere winds will be southwest to west 15 to 25 mph and gusty, except stronger across the Antelope Valley and over much of the Mojave. It will be cooler over all the region today, especially across the central portions of the state. Highs will mainly be in the 60s across the coastal and valley areas with mid-30s to upper 40s in the mountains. Precipitation amounts will generally be less than a half inch along the Central Coast, with up to an inch or so in the Sierra Foothills north of Fresno with snow above 4,000 feet.

Tonight, a few showers or areas of drizzle may spread into Southern California with a better chance for precipitation, mainly in the form of snow along the north slopes of the Grapevine area. Any precipitation that occurs south of Point Conception will be very light. Winds will turn more northerly and will slowly diminish across the area tonight and Tuesday as the storm moves east of the district. It will be warmer over the area Tuesday and Wednesday with 70s returning to some of the coastal and valley areas by then.

Another storm will move into the region late Wednesday and into Thursday. This system may track a little further south into Southern California but only light amounts of precipitation are expected, mainly over the higher terrain. Winds will increase once again across the mountains and deserts late Wednesday as this next storm approaches. Temperatures will also lower on Thursday over all the region but a modest rebound is anticipated Friday and Saturday as high pressure builds into the region.

 NWS LAS VEGAS – (NORTH & EAST OF BARSTOW TO STATE LINE)

Very strong winds will affect the region today as a potent Spring storm system moves through the region. Combined with low relative humidity and dry fuel a Red Flag Warning is in effect for parts of the lower Colorado River Valley and Mohave County.

Chances for rain and snow today and tonight will remain north of Las Vegas. Temperatures will fall back down below normal, especially west of Las Vegas today. The entire southern Great Basin and Mojave

Desert will be much cooler Tuesday. After a quiet and warmer day Wednesday, winds will increase along with isolated showers Thursday and Friday with next storm system.

FIRE WEATHER

RED FLAG WARNING in effect 9AM – 10 PM MON.

Strong winds combined with dry fuels will create high fire danger in northwest Arizona and along the lower Colorado River Fire Potential Discussion: There is a large disparity in live fuel moisture values between the southern and central portions of the state. Live fuel moisture readings across San Diego County have barely recovered from last fall’s minimums with current readings around 70%, which is far below normal for this time of year. Meanwhile, areas along the Central Coast near Big Sur and over the Sierra Foothills around Yosemite are seeing readings that are fairly close to normal. Grasses have mostly matured over the region, and are now showing signs of curing across the southern portions of the state where rainfall has been scarcer. Windy weather today may bring an elevated threat for fire activity across the eastern slopes of both the Sierra and the Cleveland National Forest. However, little if any fire activity is anticipated anywhere else in the Geographic Area due to the anticipated weather conditions today through the rest of the week.   

SPECIAL NOTES:

Santa Ana Wind Season Outlook

     Issued: Thursday, April 12, 2018

Discussion:

A fairly significant shift in the upper-air pattern occurred in March to allow for several periods of wet weather across Southern California. This shift brought slightly fewer than normal Santa Ana wind events to the region with 4 days (2) in the Los Angeles and San Diego areas respectively. The number of Santa Ana wind events has been decreasing since January and will continue to decline during the next couple of months.

Although sea surface temperatures continue to increase across the Equatorial Pacific region, La Niña conditions are still present. Most guidance suggests that SSTs will continue warming through the remainder of the spring and into the summer, with neutral conditions expected through late summer or early fall. The Pacific Decadal Oscillation (PDO) is slightly negative with probably only minor changes in SSTs occurring across the Central Pacific during the next few months. This, combined with our analog models would suggest a continuation of a near normal number of Santa Ana wind days for the remainder of April and also for the April-May time period. Normally for April the Los Angeles area experiences around 4 Santa Ana wind days, with an average of 2 days in the San Diego region.

 

While the end of Santa Ana season is nearing, the next six weeks, however, can be a crucial time as fuels begin to dry out, making them more receptive to fire. The significant rains that occurred in March led to the development of a healthy grass crop over much of Southern California which is now starting to cure. Any Santa Ana winds that occur in May could result in an increase in large fire potential. Recall that in May 2013, the Camarillo Springs Fire occurred, and in May 2014, a significant fire outbreak developed over Northern San Diego County, both events were associated with late season Santa Ana winds.

 

Summary:

While the PDO remains in a slightly cool phase, the Niño3.4 index is positive. Warming in the Equatorial Pacific region is expected through summer with neutral conditions anticipated later this summer and fall. Both the current weather pattern and our analog models suggest that there will be a near normal number of Santa Ana wind days for both the April and the April through May time periods. This time of year is often quite changeable so confidence in this forecast is moderate. Fuels will become more susceptible to fire in the coming weeks, so any significant winds that occur, especially in May, could result in significant fire activity.  SANTA ANA WILDFIRE THREAT INDEX: GREY NO RATING / 

NO RATING: Sundowner winds are either not expected, or will not contribute to significant fire activity.

 

MARGINAL: Upon ignition, fires may grow rapidly.

 

MODERATE: Upon ignition, fires will grow rapidly and will be difficult to control.

 

HIGH: Upon ignition, fires will grow very rapidly, will burn intensely, and will be very difficult to control

 

EXTREME: Upon ignition, fires will have extreme growth, will burn very intensely, and will be uncontrollable.
