SYNOP: (NWS SAN DIEGO)
RED FLAG WARNING REMAINS IN EFFECT TODAY THROUGH FRIDAY EVENING FOR GUSTY WINDS AND LOW RELATIVE HUMIDITY…

Strong north-to-northeast winds will develop across the area today, reaching San Diego County by tonight and continuing into Friday. The combination of strong wind and low relative humidity will create critical fire weather conditions at times Thursday and Friday. Lowest daytime humidity will be 5 to 10 percent with poor overnight recovery. Very low relative humidity will continue into
Saturday, but with weaker and more localized winds. There will be a slow recovery in humidity for Sunday and Monday as the onshore flow slowly increases.

Period of strongest winds… Today: Sierras, Sierra Foothills, Kern Co. Today-Fri: Ventura, Los Angeles, Orange & Inland Empire Friday: San Diego County

· Strongest wind speeds…. Sierras, Sierra Foothills: 15-25 mph, gusts 35 mph Kern County Mtns: 20-30 mph, gusts 40 mph Central Coast: 10-20 mph, gusts to 30 mph Southern CA: 25-35 mph, gusts to 70 mph

· Possible Locations of Strongest Winds… Today: Northern L.A. County, Ventura Co, Cajon Pass Friday: Banning Pass, Santa Ana Canyon, San Diego Co.

· Minimum humidity will drop into the 5-10% range across Southern CA today through Saturday. Central CA will see readings in the teens. Very poor recovery tonight and Friday night all areas.

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
RED FLAG WARNING IN EFFECT UNTIL 5 PM PDT TODAY FOR ALL OF SOUTHERN NEVADA FOR STRONG POST FRONTAL NORTH WINDS…

…RED FLAG WARNING IN EFFECT UNTIL 11 AM PDT /11 AM MST/ FRIDAY FOR THE LOWER COLORADO RIVER VALLEY FOR STRONG POST FRONTAL NORTH WINDS…

Strong north winds and low relative humidity will be seen today leading to critical fire weather concerns. Temperatures are expected to be significantly cooler today than Wednesday, but humidity values are expected to remain low. Winds will diminish over most areas late this afternoon, but are expected to remain strong down the Colorado River Valley though at least mid day Friday. As a result, a Red Flag Warning has been issued for all of the southern NV zones including zones 460, 461, 462, 463, 464 and 465, as well as the Lower Colorado River Valley which includes AZ 101, NV 466 and CA 229. The Red Flag Warning will be in effect through 5PM today for southern NV zones. Because of the elevated winds down the Colorado River, the Red Flag Warning will remain in effect through 11AM Friday.

Key Points:
• A Wind Advisory remain in place for all of southern NV, portions of southeast California, and the Lower Colorado River Valley.
• A Red Flag Warning remains in place for all of southern Nevada and the Lower Colorado River Valley.
• Both the Wind Advisories & Red Flag Warnings will be in effect until 5 PM Today for southern NV & portions of southeast CA and for the Colorado River Valley and portions of eastern San Bernardino County until 11 AM Friday.
• Gusty north winds of 35 to 45 mph will remain in place through this afternoon. Strongest winds will be along and near the Colorado River Valley where wind gusts to 50 to 60 mph will be possible through this afternoon. Winds down the river will diminish somewhat overnight, but still remain gusty between 35 to 45 mph through Friday morning. These conditions will create hazardous driving and boating conditions along with critical fire weather conditions.
• Much cooler conditions today with temperatures about 20 to 25 degrees cooler than Wednesday.

DAILY FUELS/FIRE POTENTIAL:
Large fire potential will be very high through Friday over most of Southern CA due to strong winds, low RH and dry fuels. Dead fuel moisture is close to the 95th percentile in terms of dryness and live fuels are close to critically dry levels. New starts will exhibit extreme fire behavior including long range spotting, crown runs and plume dominated fires. Gusty winds and wind shear may impede air operations this afternoon once the strongest winds arrive. A lack of RH will allow for fires to burn very actively tonight and Friday night. Cooler and more humid well may quell fire activity, but a return of onshore flow could result in a shift of the flaming front. Heavy resource demand is likely across the entire Geographic Area – including Central CA where fuel moisture is just as low. Lighter IA is expected Sunday through the first half of next week.

SANTA ANA WILDFIRE THREAT INDEX: TODAY: MODERATE
Northeast winds have begun in the mountains early this morning. These winds will spread into the valleys and foothills later this morning. Wind speeds of 25-45 mph will be common by afternoon with some gusts approaching 70 mph in northern L.A. County. Min RH will be below 10%

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:
2015: Unseasonable high pressure and warm ocean waters led to very warm October days and the warmest October nights on record from this day through 10/15. In San Diego, five out of the six highest October minimum temperatures on record occurred. The highest minimum temperature in any October was 76° on this day and again on 10/13. This is only two degrees off the highest minimum temperature for any time of year! (Only seven nights in history recorded 77 or 78°, all of which occurred during September, meaning these October nights were warmer than any night in July or August in San Diego). On this day the highest minimum temperature in October was also recorded in Chula Vista (73, only three degrees off all-time highest), Oceanside Harbor (74, only two degrees off all-time highest), and El Cajon (tied 69). On 10/13 Santa Ana recorded 78°, the highest October minimum temperature on record. The top six warmest October nights on the Chula Vista record occurred this month, and the top five in El Cajon occurred this month.

1996: Strong high pressure engulfed the Southwest. Temperatures soared accordingly in the deserts, allowing Victorville to reach 100°, the latest date in the season for a triple-digit reading on record.

1991: With and impressive reading of 106°, El Cajon set a record high for the month.

1986: Thunderstorms that started on 10/9 and ended on this day dropped 2.40 inches of rain on Mt. Laguna, 2.10 inches at Campo, 2.03 inches at Julian, 1.90 inches at El Cajon, 1.50 inches at Alpine, 1.39 inches at San Diego, and 0.41 inch at Miramar. Most of these became daily rainfall records for any October day. Hail the size of marbles was reported in San Diego’s east county. Rainwater flooded through a leaky roof at downtown San Diego police headquarters. Numerous streets flooded in south and east parts of San Diego County. Power outages occurred from lightning strikes.

1974: Ramona dipped to 32°, the earliest reported freezing temperature on record.

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

An area of low pressure is expected to form several hundred miles southwest of the southwestern coast of Mexico in a couple of days. Environmental conditions are forecast to be conducive for gradual development, and a tropical depression is likely to form over the weekend while the system moves west-northwest to northwest at 5 to 10 mph.

* Formation chance through 48 hours…low…near 20 percent.
* Formation chance through 5 days…high…70 percent.
