Marine Weather and Tides
Version 3.4 |
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxak69 pafg 202336 afdafg northern alaska forecast discussion national weather service fairbanks ak 336 pm akdt Wed jun 20 2018 Discussion An unsettled pattern will continue for the next few days along the west coast while warm and relatively dry weather is expected for much of the interior. Aloft, at 500 mb, a 544 dam low centered over nunivak island will slowly move to the west over the next few days. A ridge will continue to build over the interior and arctic coast tonight into Thursday. This ridge will be pushed to the east on Friday as a low moves to to the north in gulf of alaska. Central and eastern interior: warm temperatures are expected to continue for Thursday with temperatures in many locations in the tanana and yukon river valleys reaching the upper 70s, with some locations reaching 80 degrees. Isolated afternoon and evening thunderstorms are possible tomorrow across much of the interior as a front moves north through the interior. Scattered thunderstorms are possible tomorrow along a line from eagle to livengood where the models are showing an area of higher instability with cape values in excess of 1000 j kg along with negative LI values. Winds tomorrow afternoon are expected to kick up in the alaska range as a thermal trough just north of the range intensifies. Friday will be cooler across most of the interior. Rain showers are expected across much of the eastern interior on Friday, some of which could be locally heavy; however, at this point there is not a lot of consistency between the models in the placement and exact timing of the heaviest precipitation. West coast and western interior: a weather front will move north across the west coast late tonight into Wednesday. This will bring locally heavy rainfall to the yukon delta and lower yukon valley. Scattered showers will continue on Friday. North slope and brooks range: temperatures are expected to continue to warm over inland areas with the ridge of high pressure moving over the brooks range tomorrow. A shortwave will |
move to the north on Friday. This will bring more rainfall to the brooks range and cooler temperatures. Low level stratus and fog is expected to continue along the coast. Coastal hazard potential days 3 and 4... None. Fire weather A thermal trough will strengthen tomorrow over the tanana valley. This will cause the winds to pick up on the north side of alaska range. High temperatures tomorrow will be warmer with many locations in the tanana and upper yukon valleys reaching reaching into the 80s. Minimum relative humidity values will drop below 25 percent across much of the tanana valley. Red flag conditions are expected in the vicinity of delta junction tomorrow afternoon. We issued red flag warnings for zones 223 and 226 for Thursday in anticipation of the hot, dry and windy conditions. A front will bring isolated to scattered thunderstorms late tomorrow afternoon and evening across much of the interior. This will likely bring a lot of lightning activity to portions of the eastern interior tomorrow evening. We issued red flag warnings in anticipation of the lightning for Thursday evening for zones 220, 222 and 224. Cooler and wetter conditions are expected on Friday behind the front. Hydrology Warm temperatures aloft over the brooks range combined with heavy rainfall over the last several days and additional rainfall expected over the next couple days will produce significant rises on rivers draining the brooks range and in particular the sag river. Current forecasts keep the sag river below action stage, but we will need to monitor closely as additional rain falls over the brooks range. Recent heavy rainfall will keep many of the smaller creeks and streams in the west coast and western interior running high over the next few days. Afg watches warnings advisories Red flag warning for akz220-akz222-akz223-akz224-akz226. Small craft advisory for pkz210-pkz220. Jun 18 |

NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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. |
