Marine Weather and Tides
Version 3.4 |
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. 6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported. 5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive. |

Broad mid lvl low pressure over the bering sea containing several distinct height minima will begin to coalesce and deepen as an organized, vertically stacked low, reaching just south of st. Lawrence island early Wednesday. A series of shortwaves associated with this bering sea system will move south to north across the interior during this time, providing a setup for precip across the west coast and chinook conditions north of the ak range. By Thursday, the bering low will weaken and track eastward and high pressure will build back across the arctic shores, resulting in a more stable pattern late in the week. North slope... broad sfc high pressure centered in the northern chukchi sea continues to provide stability across the north slope. Low stratus over point barrow associated with a weak sfc trough just east of the high will erode as the high tracks eastward. The high will continue to retreat eastward towards banks island as the first of the aforementioned shortwaves reaches the north slope late Monday. Increasing cloud cover through Tuesday will be followed by areas of snow Wednesday. A leeside low will develop over barter island Wednesday and will support heavier snow north of the eastern brooks range and along the beaufort coast. High pressure will return to the coast late Thursday with clearing conditions expected thereafter. West coast and western interior... benign conditions will continue through the weekend for most of the region. Gusty NE winds across st. Lawrence island can be expected Sunday evening into Monday. By early Monday, shortwave number 1 will move north into the yukon delta, providing rain for areas east of the kuskokwim mountains. Snow may mix in at higher elevations. Heavier precip is expected Tuesday in these same locations as the sfc low nears the coast by CAPE romanzof and the second of a series of shortwaves tracks through the area. Highest |
precip totals can be expected in the nulato hills due to southeast flow and upslope forcing. Rain can be expected as far north as cape lisburne, where daytime high temperatures will reach above freezing. Showery conditions will gradually taper off through Friday as the sfc low tracks south. Central and eastern interior... southerly flow across the ak range as well as ridging aloft has combined to produce warming temperatures and clearing conditions across the tanana valley. The chinook effect will persist and amplify over the next few days and will act to shield this area from any precip associated with the shortwaves transiting the region. However, areas of the ak range can expect snow beginning Monday evening and increasing into Wednesday. Additionally, a strong southerly low-mid lvl jet will act to enhance the chinook winds late Monday into Tuesday. Very strong winds are likely across mountain peaks as well as through passes. This, combined with heavy snow accumulations over 1 ft. Will make conditions near mt. Denali particularly hazardous through Thursday. Advisories may be warranted during these times. Models... model concensus remains tight through Thursday will all solutions favoring the pattern described above. The ecmf does seem to keep the bering low significantly weaker than all other guidance, therefore the GFS was chosen as the going standard for the latter half of the week. Coastal hazard potential days 3 and 4... None. Fire weather Chinook conditions along the tanana valley will feature low rh values and warmer temperatures across the entire area as well as strong S winds spanning the northern slopes of the ak range. These winds could reach as far north as delta junction at times, resulting in abrupt shifts in wind direction and speed. These conditions will be strongest Tuesday and Thursday. Afg watches warnings advisories High wind watch for akz226. Heavy freezing spray warning for pkz210. Small craft advisory for pkz210. Cowman apr 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. |
