The Predictive Services section at the National Interagency Fire Center has issued their National Wildland Significant Fire Potential Outlook for April through July, 2012. If correct, Arizona, New Mexico, Florida, and portions of California and Nevada will experience above normal wildfire potential for the months May through July.

Below is a summary of the wildfire potential:

Significant Fire Potential

• Above Normal Significant Fire Potential is expected along the east coast from near Wilmington, North Carolina, to near Panama City, Florida, including all of the Florida peninsula; most of northwestern Nevada; foothills and inland valleys of southern California; and the lee side of the Hawai’in Islands.
• Significant Fire Potential will increase to above normal in the spring across most of Minnesota, northern Wisconsin, the upper peninsula of Michigan and northwestern Iowa; central and western New Mexico, most of Arizona, southern Nevada, far southern Utah and extreme southwestern Colorado.
• Below Normal Significant Fire Potential is expected for much of the Ohio and Tennessee Valleys, the middle and lower Mississippi Valley, and Puerto Rico. The rest of the country will have normal significant fire potential.

Climate and Drought Conditions

• La Niña will continue to weaken as oceanic trends point to warming of the equatorial Pacific through spring, favoring a neutral or weak El Niño cycle by early summer.
• Warmer than normal temperatures are expected across much of eastern two-thirds of the U.S.in March and transitioning to above normal across just the southern half of the country. Below normal temperatures are expected for the West coast and much of Alaska.
• Precipitation is expected to be below median for most of the southwest, central and southern Plains, and the Gulf coastal region including all of Florida, and southern Alaska. Above median precipitation is expected for the Northwest and northern Rockies, the Upper Midwest, theGreat Lakes region, and the Ohio and mid-Mississippi valleys.
• Drought will persist through much of the lower Atlantic and Gulf coasts, most of the southwestern and south central U.S., most of central and northern California, the western Great Basin, and the upper Mississippi valley. Drought will likely develop across the northern Plains, the eastern Great Basin and central Rockies, and southern California. There will be some improvement in the Northwest, parts of northern California, east Texas, and on the lee sides of the Hawai’in Islands.

The Predictive Services section at the National Interagency Fire Center has issued their National Wildland Significant Fire Potential Outlook for March through June, 2012. The eastern United States should experience temperatures much above normal in March, and drought conditions are predicted for the southwest, the southeast, and Minnesota through May.

Below is a summary of the wildfire potential:

• Above Normal Significant Fire Potential is expected along the east coast from near Wilmington, North Carolina, to near Panama City, Florida, including all of the Florida peninsula; most of northwestern Nevada; foothills and inland valleys of southern California; and the lee side of the Hawai’in Islands.
• Significant Fire Potential will increase to above normal in the spring across most of Minnesota, northern Wisconsin, the upper peninsula of Michigan and northwestern Iowa; central and western New Mexico, most of Arizona, southern Nevada, far southern Utah and extreme southwestern Colorado.
• Below Normal Significant Fire Potential is expected for much of the Ohio and Tennessee Valleys, the middle and lower Mississippi Valley, and Puerto Rico.
• The rest of the country will have normal significant fire potential.

The Predictive Services section at the National Interagency Fire Center has issued their National Wildland Significant Fire Potential Outlook for February through May, 2012. According to their prediction, several areas of the United States will have above normal wildfire potential during this period.

Here is an excerpt from their report:

================================================================

La Niña: La Niña remains at near moderate strength and is expected to slowly weaken during the spring months. Classic weather patterns of wet and cold in the northwest and warm and dry in the south are expected, although intensity of these cannot be directly correlated to the strength of La Niña.

Drought: Significantly above normal precipitation fell January across parts of West and North Texas and southern Oklahoma. The Northwest also received significant precipitation. However, large parts of the Southwest and the Plains states remained much below normal. Severe to exceptional drought continues across the south central and far southeastern parts of the U.S. and over parts of the upper Mississippi valley.

Fuel Dryness: Late January and early February have brought a transition to much of the U.S. The southern tier continues to see drier than normal conditions, except across some portions of Texas, where precipitation is moistening fuels even though drought conditions remain prevalent. Also, tree mortality from drought will continue to be problematic. Across much of the west, including the Great Basin fine fuels remain heavy and continuous and are largely dry or capable of quickly drying. Significant fires will be possible with the combination of ignitions and windy conditions. The formerly dry Northwestern quarter of the country has begun to see significant moistening and snowpacks are beginning to increase. In the east the northern tier will largely be near normal seasonal fuel conditions with some dryness lingering across the Great Lakes states. The southeast will continue drier than normal fuels conditions south and east of the Tennessee Valley.

The Predictive Services section at the National Interagency Fire Center has issued their National Wildland Significant Fire Potential Outlook for January through April, 2012. According to their prediction, most of the United States is in for a quiet first part of the year with the exception of parts of Minnesota, New Mexico, Texas (as usual), Georgia, South Carolina, and Florida.

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

• La Niña: La Niña conditions will continue over the tropical Pacific and typical weather patterns will return to the US after intraseasonal circulations disrupted the classic La Niña patterns over North America in December.
• Drought: Significantly above normal precipitation fell in December over parts of the front range of the southern Rockies, the central Plains and the Ohio Valley. Parts of central and west Texas, southwest New Mexico and southern Arizona also received above normal precipitation. Much of the West, the central and southern Rockies, the northern Plains and Florida received less than 50 percent of normal precipitation for the month.
• Fuel Dryness: Fuel conditions continue to improve across most of the U.S. As winter progresses and La Niña returns the northern tier of the country will see fuel conditions that are not conducive to significant fires. The far southern portions of the country, however, will begin to experience drier and warmer periods as La Niña sets in. Even though these will not be as strong as last year, expect fuels conditions to dry significantly and support significant fires across the Southwest and the far Southeast.

The Predictive Services section at the National Interagency Fire Center has issued their National Wildland Significant Fire Potential Outlook for November, 2011 through February, 2012. According to their prediction, Texas will continue to experience “extreme to exceptional drought conditions”.

The primary factors influencing these outlooks are:

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.
