Consecutive Wet Days

With Anchorage approaching the record number of consecutive days with measurable precipitation, I thought it would be interesting to see where other stations stacked up. The attached maps show the record number of consecutive days with measurable precipitation (>= 0.01") and the record number of consecutive days with at least a trace of precipitation. This was culled from the GHCN database for all Alaska stations. I decided to stick with "major" stations since they are more likely to capture days with small precipitation amounts. Ketchikan had the most consecutive days of measurable precipitation (88) and Adak had the most days with at least a trace of precipitation (203).



Here is the list that was used to make the maps above. It is sorted by max number of days with measurable precipitation.

  1. FWIW, my USFS approved rain gauge just hit the magic 1" mark in today's (9/11/13) rain in downtown Fairbanks. And more to come this eve according to NWS WX radar.

    We did have a nice summer.

  2. Brian,

    Very interesting. I would not have guessed that the number of days with measurable precip would have exceeded about 50, even at the wettest locations in Alaska.
