September had some crazy weather in the USA including some big snow storms in Montana and persistent drought in California. California also had its warmest January – September on record. Regions of Alaska had their warmest monthly temperatures record.
Major climate events NOAA is closely monitoring:
- Persisting drought in parts of the West: Heavy precipitation during September improved short-term drought conditions across the Southwest. Along the Pacific Coast, precipitation was insufficient to significantly improve drought conditions, with drought still impacting all of California. The long-term drought conditions across the region will continue to impact water resources and agriculture and increase wildfire risk. More information is available from the U.S. Drought Monitor.
- El Niño still probable later this year: According to NOAA’s Climate Prediction Center, there is a 2-in-3 chance of at least a weak El Niño developing during the next 1-2 months and lasting into spring 2015. El Niño conditions could impact temperature and precipitation patterns across the United States. More information is available from NOAA’s Climate Prediction Center.
- Transition to the cold season: September marks the end of the warm season for the United States, and over the next month freezing temperatures will bring an end to the growing season for most locations. Freezing temperatures typically impact high-elevation and northern locations first and expand southward as autumn progresses.
