This year, a combination of drought conditions, high winds and high temperatures all call for an intense fire season. Predictions indicate above-normal fire potential, and indicators suggest the onset of the monsoon season will be delayed.

Since October, we've had very low precipitation – averaging less than half of average across large portions of the state – accompanied by low snowpack and temperatures that have been well above average.

The combination of these factors, along with bursts of dry winds that are typical for the spring, gives us conditions of above-normal fire potential, which is what the Southwest Coordination Center, the main fire prediction center for our region, predicted beginning in late January.  (read more)

Notes from the Field: Dendrochronology, Wildfire, and Iron Maiden

Just how old are the forests in the Chuska Mountains in the northeastern part of the Navajo Nation? How might those forests fare in a climate that will be warmer and probably drier than anything they've ever experienced?

In early June I had the chance to tromp around in the woods with a group of experts working to answer these questions. Our intrepid leader was UA Laboratory of Tree Ring Research PhD student Chris Guiterman who—I now know—is a man with a plan. The plan goes something like this...(read more)

Southwest Climate Podcast: Impending Collision of El Niño and the Monsoon

Tuesday, June 17, 2014

In the June Southwest Climate Podcast, CLIMAS climate scientists Zack Guido and Mike Crimmins discuss the ongoing drought conditions (especially at Mike's house), the recent slowdown of a seemingly inevitable El Niño event, and potential impacts of a climate collision between the El Niño and the Monsoon. The next 6 months will be interesting…(more)
