Red Flag Warning until 06:00PM Friday.

Critical fire weather conditions are expected in the coming days over the Dolan and Glass Fires. Periods of moderate northerly winds will develop as early as Wednesday evening and last through Friday. This will combine with very low afternoon humidity and little or no nighttime recovery along with critically dry fuels. This wind event will NOT be as strong as the weekend event for the Glass Fire. However gusty winds and low humidity will create potentially dangerous fire weather conditions for the Dolan Fire, especially during the overnight hours when humidity tends to drop and ridge top winds can be strongest over the Los Padres National Forest. The National Weather Service in San Francisco has issued a Red Flag Warning...which is in effect from 1 PM Thursday to 6 PM PDT Friday. The Fire Weather Watch is no longer in effect.

* WIND...Northwest winds arrive Thursday afternoon during the peak of the burn period along with very low humidity. Northwest winds increase Thursday night into Friday morning with gusts to 25 mph and little or no humidity recovery. Breezy northerly winds continue through the Friday burn period as humidity stays very dry with continued hot temperatures.

* HUMIDITY...15 to 25 percent but locally 8-12 percent with little or no nighttime recovery in the hills.

* HIGHEST THREAT...Active portions of the Glass Fire or those areas with unsecured or open fire line.

* IMPACTS...Fire will spread rapidly due to the combination of hot temperatures, very dry fuels, breezy northerly winds and low humidity.

* AFFECTED AREAS: NORTH BAY MOUNTAINS

 

Recommended actions

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.

Tips from ready.gov


Excerpted from ready.gov
Before:

  • To begin preparing, you should build an emergency kit and make a family communications plan.

  • Plant fire-resistant shrubs and trees. For example, hardwood trees are less flammable than pine, evergreen, eucalyptus or fir trees.
    Regularly clean roof and gutters.

  • Use 1/8-inch mesh screen beneath porches, decks, floor areas, and the home itself. Also, screen openings to floors, roof and attic.

  • Keep handy household items that can be used as fire tools: a rake, axe, handsaw or chain saw, bucket and shovel.

  • Consider installing protective shutters or heavy fire-resistant drapes.

  • Clear items that will burn from around the house, including wood piles, lawn furniture, barbecue grills, tarp coverings, etc. Move them outside of your defensible space.

  • Identify and maintain an adequate outside water source such as a small pond, cistern, well, swimming pool, or hydrant.

  • Have a garden hose that is long enough to reach any area of the home and other structures on the property.

During:

  • Wear protective clothing when outside – sturdy shoes, cotton or woolen clothes, long pants, a long-sleeved shirt, gloves and a handkerchief to protect your face.

  • Close outside attic, eaves and basement vents, windows, doors, pet doors, etc. Remove flammable drapes and curtains. Close all shutters, blinds or heavy non-combustible window coverings to reduce radiant heat.

  • Close all doors inside the house to prevent draft. Open the damper on your fireplace, but close the fireplace screen.

  • Shut off any natural gas, propane or fuel oil supplies at the source.

  • Connect garden hoses to outdoor water faucet and fill any pools, hot tubs, garbage cans, tubs or other large containers with water.

  • Place lawn sprinklers on the roof and near above-ground fuel tanks. Leave sprinklers on and dowsing these strutures as long as possible.

  • If you have gas-powered pumps for water, make sure they are fueled and ready.
    Place a ladder against the house in clear view.
