SYNOP: (NWS SAN DIEGO)
Elevated fire weather conditions will continue along and near the coastal slopes of the mountains today and Tuesday with lowest daytime humidity of 10 to 15 percent and gusty northeast winds to 35 mph late at night into the morning each day. Offshore flow will weaken on Wednesday with slight cooling and recovery of humidity from the coast into the valleys. Stronger offshore flow is possible for Thursday into Friday with stronger and gusty northeast winds and low inland humidity with critical fire weather conditions possible for the mountains, valleys, and inland Orange County. A return and strengthening of onshore flow will spread cooling and higher coastal inland during next weekend.

Local north winds of 20-30 mph in/near the I-5 Corridor and Santa Barbara County early this morning.

· Northeast winds of 15-25 with gusts to 40 mph this afternoon through Tuesday afternoon over a wide area of Southern CA. Strongest winds may be in northern Los Angeles County, Banning Pass and the Santa Ana Canyon.

· Temperatures much warmer through Tuesday with some 90 degree readings in the valleys and coastal plains of Southern CA. Highs near normal across the rest of the district during the first half of the week

· Offshore winds likely returning by Thursday morning. By afternoon, some gusts over 50 mph will be possible across Southern CA. The strongest winds look to be centered on the Thursday afternoon through early Friday morning time period. The strongest winds may be across the Inland Empire and San Diego County Thursday and Friday.

· Temperatures will climb well into the 90s across Southern CA Thursday and Friday while the mountains and desert experience a cooling trend. This weekend, expect highs to drop back to near normal. Marine layer stratus may return next Monday.

· Very low RH across Southern CA today and Tuesday with minimums in the 8-15% range. Poor recovery tonight. Thursday through Saturday, Southern CA valleys and foothills will experience readings in the single digits.

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
Dry conditions expected through the week with temperatures slowly climbing to 5-8 degrees above normal through Thursday. Brief periods of northerly winds expected, though will ramp up on Thursday, particularly down the Colorado River Valley and will die back down for the weekend. Minimum RH values expected to be in the lower teens through the early part of the week before dropping to the single digits on Thursday. This,
coupled with the increase of northerly winds could result in increased fire weather concerns.

SPECIAL NOTES:

DAILY FUELS/FIRE POTENTIAL:
Locally gusty offshore winds will result in elevated large fire potential across Southern CA today and Tuesday. New starts may burn actively tonight due to poor recovery and breezes on the mid slope elevations. Later this week, there will be a high risk of large fires due to a return of gusty winds. The hot temperatures will be the most notable weather element with the next wind event as readings may be in the upper 90s and RH will drop into the 3-8% range. Very rapid rates of spread will be possible in windy areas. Even some aspects which are not exposed to the offshore winds may see very active fire behavior due to very low fuel moisture conditions. Dead fuel moisture is close to record low readings for this time of year while live fuels are uniformly dry at near critical moisture levels. Expect aggressive fire behavior, long range spotting and burning at night through Saturday. IA may be heavy once again Thursday.

SANTA ANA WILDFIRE THREAT INDEX: TODAY: YELLOW MODERATE
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.

============================================================
THIS DAY IN WEATHER HISTORY:
2007: Very strong Santa Ana winds developed on this day and continued through 10/23. A gust of 85 mph was recorded at Fremont Canyon, 79 mph at San Bernardino, 75 mph at Descanso and Mira Loma, and 74 mph at Fallbrook and Rancho Cucamonga. Some locations experienced winds at least 45 mph for more than 36 consecutive hours. Winds caused at least $60 million in damage and destruction to buildings, fences, vehicles, etc. The devastating wildfires of 2007 were fanned by these winds. These fires caused one million Californians to evacuate, the largest mass evacuation in California history. Several notable fires that started on this day include the Witch Creek, Harris, and Santiago Fires. The Witch Creek fire eventually grew into the sixth largest wildfire in California since 1932, consuming 197,990 acres, 1,650 structures, injuring 40, and causing two fatalities. The combined cost of damages and fighting the fire was estimated at more than $1 billion. The Harris and Santiago Fires would scorch 90,440 and 28,445 acres respectively and cost a combined $43 million to fight.

2004: A waterspout was spotted two miles southwest of North Island.

1965: Newport Beach reached 96°, the all-time highest temperature on record.

1957: Widespread thunderstorms developed on 10/20 on this day. Hail drifted to 18 inches deep in East LA. Waterspouts were observed off Point Mugu and Oceanside.

1949: It was 34° in Santa Ana, the lowest temperature on record for October. This also occurred on 10/12/1924 and 10/31/1935.
==================================================================
TROPICAL EAST PACIFIC REPORT:
For the eastern North Pacific…east of 140 degrees west longitude:

Showers and thunderstorms associated with a well-defined low pressure system located more than 1000 miles east-southeast of the Hawaiian Islands have increased and become a little better organized since yesterday. Environmental conditions appear conducive for additional development of this system, and a tropical
depression could form during the next couple of days while the system moves westward to west-northwestward at about 10 mph.
Upper-level winds are expected to become less favorable for development by the middle to latter part of the week. The low is expected to cross into the central Pacific basin later this morning.

* Formation chance through 48 hours…medium…40 percent.

* Formation chance through 5 days…medium…40 percent.
