10/04/09 08:31:32 No    
09/25/09 08:49:58 Yes   The Live Fuel Moisture around Western Utah County is below normal values for this time of year. The recent pattern of warmer than normal max temperatures and below normal min RH have resulted in NFDRS indices consistently above normal. Given Red Flag conditions, large fire potential is high, especially near Utah Lake where the influence of the lake on local winds will exacerbate extreme fire behavior.
09/15/09 19:00:01 No   Western Utah County has recently received some precipitation and much higher RH values. LFM in Juniper and Sagebrush is near normal values for this time of year. Fire potential has moderated significantly due to the combination of these factors.
09/15/09 18:54:24 No   Western Utah County has the potential for large fire growth given Red Flag criteria due to the extended warm and dry weather in Northern Utah. Although LFM in Juniper has been trending higher, the samples are still at or below the average for this time of year. Sagebrush LFM is near normal. However, ERC indices have reached historical extreme values, and 1000-hour fuel moisture has been steadily decreasing.
09/12/09 09:57:29 Yes   Western Utah County has the potential for large fire growth given Red Flag criteria due to the extended warm and dry weather in Northern Utah. Although LFM in Juniper has been trending higher, the samples are still at or below the average for this time of year. Sagebrush LFM is near normal. However, ERC indices have reached historical extreme values, and 1000-hour fuel moisture has been steadily decreasing.
09/04/09 15:25:26 Yes   Western Utah County has the potential for large fire growth given Red Flag criteria. Live fuel moisture in Juniper woodland is at critically dry levels (63-70%). Sagebrush LFM is 60-70% (slighly below normal) and will contribute to extreme fire behavior. Larger fuel (1000-hr) moisture has dropped slightly below normal levels.

07/18/09 00:44:22 Yes   Live fuel moisture in Juniper woodland is at critically dry levels (<70%). Sagebrush LFM is near 80% and will contribute to fire behavior. Larger fuel (1000-hr) moisture is rapidly dropping; however, fuel moisture is near normal.
07/08/09 21:52:20 Yes 6,500 Live fuel moisture in Juniper woodland is at critically dry levels (<70%). Sagebrush LFM is near 80% and will contribute to fire behavior. Larger fuel (1000-hr) moisture is rapidly dropping; however, fuel moisture is above normal.From 6500-7500', grass may still be growing above normal loading due to early summer moisture at these bench locations.
07/08/09 06:44:05 No   Live fuel moisture in Juniper woodland is at critically dry levels (<70%). Sagebrush LFM is near 80% and will contribute to fire behavior. Larger fuel (1000-hr) moisture is rapidly dropping; however, fuel moisture is above normal.From 6500-7500', grass may still be growing above normal loading due to early summer moisture at these bench locations.
07/08/09 06:38:39 No   Due to the abundance of Cheatgrass, the potential exists for large fire growth in this zone given Red Flag criteria. Live fuel moisture in Juniper woodland is at critically dry levels (<70%). Sagebrush LFM is near 80% and will contribute to fire behavior. Larger fuel (1000-hr) moisture is rapidly dropping; however, fuel moisture is above normal.
07/06/09 06:30:17 Yes 6,500 Due to the abundance of Cheatgrass which has cured below 6500 feet, the potential exists for large fire growth in this zone. In addition, live fuel moisture in Juniper woodland is critically dry (<70%). Sagebrush has just recently dropped below 120% and will contribute to fire behavior where an understory of Cheatgrass is present to pre-heat the live fuel. Larger fuel (1000-hr) fuel moisture is dropping; however, it is still way above normal.
06/28/09 10:52:29 Yes 6,500 Due to the abundance of Cheatgrass which has cured below 6500 feet, the potential exists for large fire growth in this zone. In addition, live fuel moisture in Juniper woodland is critically dry (<70%). Sagebrush has just recently dropped below 120% and will contribute to fire behavior where an understory of Cheatgrass is present to pre-heat the live fuel. Larger fuel (1000-hr) fuel moisture is dropping; however, it is still way above normal.
06/28/09 10:36:51 Yes 6,500 Due to the abundance of Cheatgrass which has cured below 6500 feet, the potential exists for large fire growth in this zone. In addition, live fuel moisture in Juniper woodland is critically dry. Sagebrush has just recently dropped below 120% and will contribute to fire behavior where an understory of Cheatgrass is present to pre-heat the live fuel. Larger fuel (1000-hr) fuel moisture is dropping; however, it is still way above normal.
06/19/09 03:45:44 No   Cheatgrass has cured below 6000 feet with a possible second growth at the lower elevations. From 6000-7500', grass may still be growing above normal loading due to recent moiture at these bench areas. Live fuel moisture (sagebrush) has dropped below 120%, meaning that sage will contribute to fire behavior characteristics given a cured grass understory. However, this area is not yet in a "critical" fuels condition.
06/19/09 03:43:18 No   Cheatgrass has cured below 6000 feet with a possible second growth at the lower elevations. From 6000-7500', grass may still be growing above normal loading due to recent moiture at these bench areas. Live fuel moisture (sagebrush) has dropped below 120%, meaning that sage will contribute to fire behavior characteristics given a cured grass understory.

09/06/08 11:03:26 Yes   The Pleasant Grove RAWS received 1.14" in the 8/31 - 9/1 with 12 hours of duration. Consequently, fuel moisture temporarily increased. However, due to the dominance of 1-hour fuels throughout this zone and lack of precipitation with relatively low RH values, critical fuel conditions persist.
09/06/08 10:40:10 Yes   Precipitation received 8/31-9/1 was a quarter to half inch; duration was typically less than 6 hours (total). Consequently, drought conditions persist with less than 65% of normal precipitation since January. Live fuel moistures in sagebrush and juniper are less than 60-75% and 80% respectively. The 1000-hour fuel moisture is 5-6%.
09/03/08 17:11:50 Yes   Precipitation received 8/31-9/1 was a quarter to half inch; duration was typically less than 6 hours (total).

05/30/08 09:32:52 No   Drought conditions have moderated across Northern Utah due to a week of cool & wet weather. Above normal snow pack and cooler than average temperatures this spring have kept fuels moist and delayed the onset of fire season, especially above 7500’.

05/20/08 18:04:50 No   Drought conditions are expanding and intensifying across Northern Utah. Above normal snow pack and cooler than average temperatures this spring will help keep fuels moist and delay the onset of fire season above 6500’. However, critical live fuel moisture levels sampled in Juniper and the persistence of drought will likely result in extremely high fire potential and mortality in Juniper woodland fuel types.
