Atmospheric River in the Pacific Northwest and Northwest California Early This Week

An atmospheric river event will bring heavy rains and rising snow levels to the Pacific Northwest and northwest California early this week. Snow levels will rise above 8,000 feet, and 4 to 7 inches of rain is forecast for the southwest facing slopes of the mountains. Minor river and localized flooding will be possible. In the east, winds decrease by Monday, and the week will be relatively dry. Read More >

PEAC Research


A major focus of ongoing applied research at PEAC is the investigation of statistical correlations between ENSO and sea level. Seasonal sea level forecasts, discussion and verification are issued every 3 months in the Pacific ENSO Update newsletter.

Statistical studies on regional climatology and the ENSO cycle are underway at the University of Guam (UOG) and the University of Hawaii (UH). This cooperative research activity is being led by the Water and Environmental Research Institute (WERI) of the UOG, through a sub-grant from PEAC. The studies aim to develop ENSO-related impact criteria for the Islands, through examination of:

  • Historical floods and droughts, their causes, impacts on agriculture, and other information concerning water resources in each regional area;
  • The pattern of severe weather phenomena such as hurricanes and typhoons in each regional area;
  • The distribution of commercially important fish species within each regional area, in cooperation with NOAA's National Marine Fisheries Service; and
  • Relationships with the ENSO cycle, with an aim for developing predictive forecasts of 6 - 18 month lead times for the region.
