Hydrologic Outlook issued October 27 at 3:36PM AKDT by NWS Fairbanks AK

ESFAFG Areas of concern are between Nome and Council, particularity streams and rivers draining the south aspects of the high elevation terrain of the Seward Peninsula. Rivers and streams in the Nome and Council area are already high following rainfall over the weekend. 1-3 more inches of precipitation are expected by the end of the week which will keep water levels high. No flooding is expected at this time, however residents living near local rivers and streams should be vigilant of the potential for ice in culverts and other stream passage structures to restrict flow resulting water flowing over roads in affected areas.

When a severe thunderstorm warning is issued, the storm may produce damaging winds, large hail, dangerous lightning, and heavy rain. In some cases, heavy rainfall produced by a severe storm can also lead to flash flooding. Do not drive vehicles through flooded areas. The water depth or fast flowing water/mud/debris from a flash flood will make road conditions unsafe. Do not rely soley on data presented here or other third-party websites - always check your official national and local weather service agency website, socials, radio and/or TV stations for making critical decisions related to weather events.

Please carefully read each posted Warning and Alert as it relates to the area(s) being affected.
