TX Critical Fire Danger

#1 Postby jeff » Sat Dec 31, 2005 12:52 pm

Serious fire weather event expected Sunday.

Deepening trough along the front range of the Rockies will shift winds around to the WSW late tonight and early Sunday. Air flow will downslope off the Sonora desert of NE Mexico brining near record high temperatures and very dry surface air.

RH values should fall below 30% across much of TX by midday Sunday as strong mixing of WSW winds begins. Winds will increase from the 10-15mph range in the morning to 20-30mph by early afternoon. With drought conditions across the state and surface fuels very dry coupled with very favorable atmospheric conditions an extreme fire danger will be in place for Sunday.

A Fire Weather Watch is currently in effect for most of TX with Red Flag Warnings already up for N TX for today and Sunday. Fires still not completely contained from Tuesday will likely flare up and given the ideal conditions will spread extremely quickly. Given the forecasted wind speeds of 20-30mph with gust of 40mph forward motion of any fire will be quick with little time for reaction. Fire fighting will be defensive for much of Sunday as current wind and RH forecast will make most fires uncontrollable.

Winds will weaken Sunday night allowing some containment and a slowing of the burn rates. Dry conditions will continue for the next 10-14 days with another critical fire weather day Tuesday.

169 counties are currently under burn bans and many counties have restrictions on ariel fireworks including Harris. The fine for either ban is 500 to 2000 dollars.

Dangerous wildfire conditions remain across all of TX

In the last 24 hours, 58 fires have developed across the state burning 72 homes including 32 houses in the town of Riggold, TX. 122 aircraft missions were flown yesterday alone dropping a total of 147,350 gallons of fire retardant chemical. Since Dec. 26th, 139 large fires have been reported across the state burning 80,219 acres. 44,442 of the 80,219 acres were burned yesterday.

Current:

Red flag conditions will once again be met across central and north TX today. Ongoing fires will burn generally ESE and SE today with WNW to NW winds behind a cool front early this morning. Winds should remain less than 20mph allowing for significant ariel attack from rotary aircraft. RH values recovered little overnight as W winds brought dry air eastward from the southern Rockies. Fire containment is critical today as conditions will greatly worsen on Tuesday.

Tuesday:

Severe fire weather conditions return as dry WSW winds increase ahead of another frontal system. RH values are expected to fall to less than 20% across a large part of the state. Winds will increase into the 25-30mph range with gust above 40mph grounding rotary aircraft. Once again fire fighting operations will mainly be defensive as the fires will burn hot and fast and out of control along multiple fronts.

Extended:

There is no relief in sight for the next 7-10 days as several fast moving dry fronts pass through the state will little or no rainfall. Each front will produce a period of dry gusty winds creating extreme fire danger.

Very dangerous fire weather event expected today and Thursday.



Residents should be prepared for large fast moving grass and rangeland fires.



Extremely dry conditions coupled with dead surface fuels, increasing winds, and low RH values will create very hazardous fire weather conditions today and Thursday. Conditions will be similar to Sunday and last Tuesday when entire towns and subdivisions across N TX burned.



Current:

254,555 acres have burned since Dec 26 in 159 major fires. The TX forest service along with federal agencies flew 659 aircraft missions yesterday dropping a total of 806,780 gallons of fire retardant chemicals on 20 large fires. 238 structures have been lost in the last week. Offensive fire fighting operations yesterday will change to defensive today as strong west winds ground water dropping aircraft.



Today:



Critical fire weather conditions will be met across central and north TX. After sunrise winds will increase out of the SW ahead of a cold front over the TX panhandle. Temps. will warm well into the 70’s by early afternoon with RH values falling to less than 25%. Winds will increase to 15-25mph with gust of 35mph. Ongoing fires will spread quickly along their east and north fronts with fast burn rates. Rotary aircraft will be grounded due to the strong surface winds and fires will likely burn out of control through the late evening.



Thursday:



Extreme fire danger for all of central, north, and SE TX. Cold front will move through the state dropping RH values to less than 20% during the afternoon hours. Pressure gradient tightens and NW surface winds increase to 20-30mph during the late morning. 20 ft winds of 20mph or greater is expected east of I-35 with good near surface mixing. Strong surface winds coupled with dry fuels and very low RH values will result in numerous fast moving wildfires. Gusty winds will ground rotary aircraft and fire fighting operations will be reduced to saving structures instead of fire containment. The potential is high for multiple large fires with fast burn rates along multiple fronts.



N TX fires:

Ranger Hill Fire (Eastland Co): 2,000 acres burned. Fire contained

Walnut Bend Fire (Cooke Co): 5,600 acres burned. 39 homes burned. Fire contained

Canyon Creek Fire (Hood Co): 137 acres burned. 47 homes burned. Fire contained

Balch Springs (Dallas Co): 20 acres burned. 2 homes lost. Fire contained

Kennedale (Tarrant Co): 300 acres burned. Numerous homes threatened with 12 burned. Fire contained

Ringgold Fire (Montague Co): 41,000 acres burned. 32 homes lost. Fire contained



Wildfire protection:



Residents should be extremely mindful of the current fire situation and take all appropriate measures to help prevent fire ignition and spread.



Actions that can be taken to help protect your property:



Keep tall grass and brush cleared at least 50-100 feet front your structure.

Keep surrounding grass watered and moist.

Have water hoses attached to outside facets at all times.

Should a fire approach your area turn on outside water systems and wet your roof.

If told to evacuate do so quickly and orderly.
