Wildfire potential, October 2011 through January 2012

The Predictive Services section at the National Interagency Fire Center has issued their National Wildland Significant Fire Potential Outlook for October, 2011 through January, 2012. According to their prediction, most of the United States is in for a quiet autumn and early winter with the exception of the southeast.

According to NIFC, the primary factors influencing these outlooks are:

  • La Niña: La Niña conditions have redeveloped, as evidenced by a marked cooling of the equatorial Pacific. It is not unusual to have a second La Niña after one of such magnitude as the 2010-11 event. However, the impacts may be greater given the degree of drought across much of the south central and southeastern U.S.
  • Drought: Extreme to exceptional drought will persist across Texas, eastern and southern New Mexico, Oklahoma, southern Kansas, western Louisiana, Georgia and western South Carolina.
  • Fuel Dryness: A significant change in fuel conditions occurred across much of the west in the latter part of September. Cooler temperatures and increasing humidity coupled with shorter days and burning periods caused indices and fuel moistures to dip to normal or below normal. Even with short warming and drying periods much of the West will not return to any significant conditions or level of concern this season. The exception may be Southern California where near normal conditions currently exist and offshore wind events remain possible through the fall. Drought conditions persist across a portion of the Great Lakes region, however with recent moisture and decreasing temperatures, fuels will not likely recover to the point of causing above normal significant fire potential after the early portion of October. Drought will persist and worsen across much of the southern U.S. from Texas through North Carolina. With leaf fall already underway and significantly below normal precipitation likely, fuel conditions will continue to be critical. The lee side of the Hawaiian Islands will also remain in a drought and fuels conditions will continue to be dry.

Wildfire potential, September through December, 2011

The Predictive Services section at the National Interagency Fire Center has issued their National Wildland Significant Fire Potential Outlook for September through December, 2011. If their prediction holds true, it looks like average or below average wildfire potential for most of the United States, except for Texas, Oklahoma, and the southeast.

Wildfire potential, August through November, 2011

The Predictive Services section at the National Interagency Fire Center has issued their National Wildland Significant Fire Potential Outlook for August through November, 2011. According to their prediction, most of the western United States is in for a quiet late summer and fall, with the exception of Texas and Oklahoma in August, and most of the southeast except for Florida from September through November.

Wildfire potential, July through October, 2011

The Predictive Services section at the National Interagency Fire Center has issued their National Wildland Significant Fire Potential Outlook for July through October, 2011. If this turns out to be accurate, it looks like there will be average or below average wildfire potential beginning in July, except for Texas — of course. When it comes to wildfires over the last 8 months or so, if it were not for bad luck, Texas would have no luck at all.

Firefighters in Arizona and New Mexico have both been extremely busy during the last 30 days, with both states experiencing record-breaking fires, larger than any in recorded history. Here’s what the outlook says about that area:

Southwest: Above normal significant fire potential is expected across the northwestern one-third to one-half of Arizona as well as sections of northwestern New Mexico in July. Much of the remainder of the Southwest will transition from above normal to normal during the first 7-10 days of the month. Seasonal trends indicate moisture under the subtropical ridge will produce periods of increased rainfall over the region. However, conditions in the northwestern parts of both Arizona and New Mexico may linger in high fire potential past mid-month until deeper moisture and precipitation can migrate to those areas and reduce the threat. Temperatures are expected to be above normal for most of the area while precipitation is expected to be normal with slightly below normal over western Arizona.

Normal significant fire potential is expected for the entire Southwest for August through October. Normal to slightly above normal monsoon activity could produce above normal precipitation for the period, especially near the continental divide and eastward. The western Arizona lowlands could see normal precipitation. Temperatures are expected to be normal to slightly above normal through the period.

Wildfire potential, June through September, 2011

Today the Predictive Services section at the National Interagency Fire Center issued their National Wildland Significant Fire Potential Outlook for June through September, 2011. If this turns out to be accurate, it looks like it will be a quiet or average summer season for the United States, with the exception of portions of Arizona, New Mexico, west Texas, central Alaska, and Florida.

The primary factors influencing these outlooks are:

  • La Niña: La Niña continues to weaken with neutral conditions expected by July. However, soil moisture extremes resulting from La Niña will continue to affect temperature and precipitation patterns through the season. Temperatures will generally be below average with above average precipitation in areas where soil moisture is significantly above normal, until.
  • Drought: Drought will continue across much of the southern third of the U.S. with some improvement expected along the Gulf Coast and in parts of Texas and the Southwest.
  • Fuel Dryness: Fuel conditions across the southern tier of states are expected to continue to be dry through June, gradually improving across west Texas, the Gulf Coast and Florida as the month progresses. Across the northern tier heavy snow and precipitation this spring has delayed green up and curing, generally delaying the onset of fire season.

Wildfire potential, May through August, 2011

The Predictive Services section at the National Interagency Fire Center issued their National Wildland Significant Fire Potential Outlook for May through August, 2011. If this turns out to be accurate, it looks like it will be a quiet or average summer season for the United States, with the exception of portions of the southwest and Florida.

The primary factors influencing these outlooks are:

  • La Niña: The ongoing La Niña influence is forecast to weaken through early summer of 2011 and return to neutral conditions.
  • Drought: Drought will persist across portions of the southwestern U.S. with improvement expected over the southeastern U.S. and portions of Texas.
  • Fuel Dryness: Dryness observed over Florida and the extreme southeast states during spring will diminish by June. Unusually dry areas with above normal significant fire potential will expand westward and northward across New Mexico and Arizona through the summer while easing through much of Texas.
