Corrected national weather service fairbanks ak 643 am akdt Fri oct 20 2017 Discussion Aloft, at 500 mb, a 496 dam low currently near point lay will move over kotzebue sound by 6 am Friday. By 4 pm on Friday the low will be near nome and by 4 am Saturday it will be near emmonak. The low will then persist over the yukon delta through Sunday night. The GFS is producing the most QPF with these snow showers for zone 213. The NAM and european are both showing less qpf. We leaned more towards the NAM for pops and qpf. At the surface, a 989 mb low west of kivalina will move south to near nome as a 986 mb low by noon Fri then weaken slowly over the yukon delta Saturday evening. A 992 mb low 60 nm north of barter island will persist through Friday, then move to near barrow as a 992 mb low by 4am sat. This low will track down the west coast and be near saint lawrence island as a 995 mb low Sunday afternoon. West coast and western interior: winter weather advisories remain in effect for zones 207 (south of CAPE krusenstern) and 213. Conditions in zone 207 should improve this morning as the low continues to dive south. For zone 213 snow and blowing snow will continue through Saturday evening before conditions start to improve. Snow showers will continue into Sunday but winds will diminish slowly on Sunday. In addition to the snow and blowing snow there is at least some possibility that freezing spray from the bering sea could be blown onshore by the strong winds |
resulting in small amounts of ice accumulating on structures close to the shore. High surf is also a concern due to the strong northerly winds in zone 213 with this system. North slope and brooks range: low pressure tracking across the north slope will bring snow showers for barrow and areas to the west through Friday night. Winds will increase for barrow this morning from the northeast around 20 to 30 mph then switch to the southeast Saturday morning. Due to the short duration and wind direction not expecting any high surf issues for barrow. Central and eastern interior: some stratus and flurries light snow showers over the eastern interior this morning. Areas that are clear are experiencing cold temperatures. Fort yukon and bettles are below zero this morning. More cold morning low temperatures are expected this weekend. Coastal hazard potential days 3 and 4... None. Afg watches warnings advisories High surf advisory for akz213. Winter weather advisory for akz207-akz213. Heavy freezing spray warning for pkz225-pkz230-pkz235-pkz240- pkz245. Small craft advisory for pkz200-pkz220-pkz235. Gale warning for pkz210-pkz225-pkz230. Jk oct 17 |

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
