The National Significant Wildland Fire Potential Outlook issued today by the Predictive Services section at the National Interagency Fire Center continues to have generally good news for those concerned about wildfires. Similar to the prediction released a month ago for May, the only area in the United States likely to have above normal wildfire potential this month are the south portions of Arizona and Florida. That is expected to change in June with the addition of locations in California and parts of Nevada, Utah, Colorado, and New Mexico.
The data from NIFC shown here represents the cumulative forecasts of the ten Geographic Area Predictive Services Units and the National Predictive Services Unit.
Below:
- An excerpt from the NIFC narrative report for the next several months;
- More of NIFC’s monthly graphical outlooks;
- NOAA’s three-month temperature and precipitation forecasts;
- Drought Monitor;
- Keetch-Byram Drought Index.
“Overall, the entry into the season is expected to be normal; however, there are areas of concern emerging for the summer months. While the Pacific Northwest received beneficial precipitation in late April, the overall pattern has been warm and dry which may be problematic for Oregon and Central through Eastern Washington. Northern California and the Great Basin area are also areas to monitor closely for Above Normal significant wildland fire potential as fuels continue to dry and cure. Additionally, fine fuel loading is expected to be above average for the third consecutive year in the lower elevations. Those fuels will dry and cure, becoming receptive to fire by mid-June.
“Other locations across the West and in Alaska can expect overall Normal conditions, though there could be pockets of Above Normal potential and activity along the Mexican Border in May and June before the anticipated arrival of a moderate monsoon in early July which should diminish fire activity in the Southwest while increasing activity further north across the Great Basin, Northern California, the Pacific Northwest, and the Northern Rockies by July.”
