SYNOP: (NWS SAN DIEGO)
Elevated fire weather conditions will continue today for the inland valleys and coastal slopes of the mountains with lowest daytime humidity around 15 percent with locally gusty east winds in the morning to 30 mph. Onshore flow will return and strengthen for tonight and Thursday. This will spread cooling and higher
coastal humidity inland with southwest to west winds in the mountains and deserts during Thursday afternoon and evening with strongest gusts to around 45 mph. There will be a brief period of northerly flow on Friday morning with gusty north winds on the coast slopes of the San Bernardino County mountains and below the Cajon Pass with strongest gusts to around 35 mph. Weaker onshore flow then prevail through Saturday. Northerly offshore flow will develop on Sunday and strengthen, becoming northeasterly for late Sunday into Tuesday. The strongest and most widespread northeast winds are expected from late Sunday night into Monday afternoon with the winds weakening and decreasing in coverage for Monday night into Tuesday morning. Elevated fire weather conditions are expected to develop on Sunday along and below the coastal slopes of the mountains with critical conditions developing late Sunday night or early Monday and continuing through much of Monday.

Highs in the 70s in the mountains to the lower 90s in the valleys today. Temperatures will cool back into the 70s in the valleys Thursday through Saturday. But expect highs to climb back into the 80s across Southern CA by Sunday and Monday.

· Light winds today, but north winds of 20-35 mph with gusts to 50 mph will be possible Santa Barbara County and the I-5 Corridor Thursday night into Saturday. Some gusts may approach 60 mph Friday night in these areas.

· West winds of 25-40 mph will be possible in the Kern County Mountains, Antelope Valley and Banning Pass Thursday and Friday.

· Winds transitioning to a northeasterly offshore direction Sunday. Sunday night into Monday, winds of 20-30 mph with gusts to 45 mph will be possible. Offshore winds will slowly abate Tuesday.

· Minimum RH dropping into the single digits across Southern CA Sunday. Poor recovery expected through at least next Wednesday.

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
Dry and tranquil weather today will give way to increasing winds and moderate cooling Thursday and Friday and again late Saturday and Sunday as fast moving systems sweep across the western region.

KEY POINTS
Wind gusts around 40 mph will be possible Thursday afternoon and evening primarily for the western Mojave Desert of San Bernardino County from Barstow northward.

CONFIDENCE AND DETAILS
San Bernardino County
MODERATE Confidence Hazardous crosswinds, especially for high profile vehicles on north/south roadways.
LOW Confidence Reduced visibility due to blowing dust and sand.

Details:
THURSDAY AFTERNOON AND EVENING
Sustained west winds 20 to 30 mph with gusts possibly around 40 mph can be expected Thursday afternoon across the western Mojave Desert. The winds will persist into Thursday evening before becoming northwest with speeds gradually decreasing to less than 25 mph by early Friday morning.

DAILY FUELS/FIRE POTENTIAL:
Large fire potential will be elevated beginning Thursday evening across the Santa Ynez Range and northern Los Angeles County due to gusty north winds. The I-5 Corridor may see the strongest winds over the next few days and the highest potential through Saturday night may be the eastern flank of the Los Padres N.F. and the northwest corner of the Angeles N.F. Sunday through the first half of next week, the strongest winds may be across the Banning Pass, Santa Ana Canyon and Cleveland N.F. Although this offshore wind event is not expected to be as strong as last week’s, fuel moisture will be lower going into next week. Dead fuels are close to historically low moisture conditions for this time of year while live fuels are close to critically dry levels. Rapid rates of spread will be possible with new starts in wind prone areas the next few days. Resource demand may become heavy with a premium placed on successful IA.

SANTA ANA WILDFIRE THREAT INDEX: TODAY: 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.

TROPICAL EAST PACIFIC REPORT:
For the eastern North Pacific…east of 140 degrees west longitude:

Showers and thunderstorms have become more concentrated during the past several hours near an elongated area of low pressure located about 100 miles south-southwest of the coast of Guatemala. Environmental conditions are conducive for development of this system, and a tropical depression or tropical storm is expected to form tonight or on Wednesday while the system moves west-northwestward at about 10 mph, toward the coast of southeastern Mexico. Regardless of development, heavy rainfall currently occurring across Costa Rica, Nicaragua, Honduras and El Salvador is forecast to spread westward over Guatemala tonight, and across southern Mexico on Wednesday. These rains could cause flooding and mudslides, especially in mountainous areas. Interests in southeastern Mexico should monitor the progress of this system.

* Formation chance through 48 hours…high…90 percent.

* Formation chance through 5 days…high…90 percent.

A large area of disorganized showers and thunderstorms centered about 1200 miles southwest of the southern tip of the Baja California peninsula is associated with a surface trough of low pressure. Some development of this system is possible during the next few days while the system moves little.

* Formation chance through 48 hours…low…near 0 percent.

* Formation chance through 5 days…low…20 percent.
