Jim Byrne KCOY Weatherman: Drought Information and Updates

Get the latest drought information from Jim Byrne. The former KCOY Weatherman is a meteorologist with ten years of scientific expertise as a geotechnical/environmental technician.

Below is the latest data gathered by Calclim, a joint effort between the Scripps Institution of Oceanography and the Western Regional Climate Center, and sponsored by the California Energy Commission.

California Drought Monitor

According to Calclim, their Drought Monitor focuses on broad-scale conditions. Jim Byrne, a former KCOY Weatherman, reminds that local conditions will still vary.

  • West California – Experiencing severe drought conditions
  • Central California – Experiencing moderate to abnormally dry drought conditions
  • Silicon Valley to North California – Both are experiencing abnormally dry drought conditions
  • South California – Experiencing moderate drought conditions

National Drought Mitigation Center West Report

Based on the map provided by the National Drought Mitigation Center and a report prepared by Dr. Deborah Bathke, an upper-level trough persisted in the West the week of Feb 27. This brought cool temperatures to all areas and moderate to heavy precipitation to parts of Idaho, western Oregon, and Washington, the San Juan and Snowy Ranges in Colorado and Wyoming, and the Sierra Nevada.

Seasonal precipitation deficits intensified as abnormal dryness developed in northeastern lower Idaho. Meanwhile, southeast Utah experienced severe drought conditions, registering water year precipitation and snow water equivalent marks in the lowest percentiles.

In southern California, particularly urban areas experiencing severe drought conditions, there has been no change due to the lack of rain. The state is still embroiled in widespread water supply issues.

Other Drought Information

According to the Executive Update of the California Data Exchange Center of the Department of Water Resources, as of January 31, 2018, hydrologic conditions in California were:

  • Precipitation – 60% of average to date
  • Runoff – 55% of average to date
  • Reservoir storage – 105% of average to date

Jim Byrne reminds readers to check back here on his blog for next update which is likely to be released on March 15, 2018. The update will contain data conditions for February 28, 2018.
