Water Supply Outlook for February 1, 2010

Record breaking temperatures and below average precipitation have water managers concerned that there will not be enough runoff to fill reservoirs and supply irrigation and municipal systems to adequate levels this summer. With temperatures averaging up to 8 degrees above normal recreationists and spectators are looking at the potential of a dismal season for winter sports, including the upcoming winter Olympics just to the north of us in Vancouver, British Columbia. Sea Tac Airport set a new record average temperature at 47.0oF. Seven other cities in WA had temperatures that either tied records or fell within the top 12 since records have been kept. Long-lead forecasts are still calling for below average precipitation and above average temperatures. We may be looking to break even more records if these conditions persist.
