Marine Weather and Tides
Version 3.4 |
10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Scattered showers will continue tonight across the waters as a weak cold front moves through the region. Northwest winds will increase into tomorrow as a coastal trough develops over southern california while high pressure builds offshore. Moderate to large northwest swell will gradually subside into early next week. The combination of gusty winds and large combined seas will create hazardous seas conditions through tomorrow evening, particularly for smaller vessels. Southerly winds will return later on Monday ahead of the next weather system.

Area Forecast Discussion National Weather Service Sacramento CA 238 PM PST Sat Dec 14 2019
SYNOPSIS. Light Valley rain and mountain snow through late tonight. Mountain travel delays are possible. Drier weather returns Sunday and early next week. Unsettled conditions are possible beginning the middle of next week.
DISCUSSION. A weak system currently along the coast will spread inland this evening and increase snowfall over the mountains. Snow levels are near 5000 feet in the Sierra but will drop this evening to around 4000 feet. Up to four inches of snow is expected with local amounts up to 6 inches. Further north snow levels will lower this evening to around 2000 feet but only light amounts of snow is expected with accumulations up to 2 inches. For the valley amounts should generally stay less than a tenth of an inch.
Conditions will be clearing up during the day and the valley should see some sun. The western slopes will likely stay mostly cloudy all day. Some patchy fog may occur in the morning hours in the valley and mountain valleys.
High pressure will build over the region and persist into Tuesday when another system begins to approach the coast. Some patches of fog each morning may continue into Tuesday with dry conditions. Morning lows will be in the 30s for the valley with some local areas possibly down to around 30 degrees. Mountain valleys will likely lower into the teens.
EXTENDED DISCUSSION (Wednesday THROUGH Saturday).
The ensemble model indicates some chances for precipitation starting along the coastal range late in the day on Tuesday. The low passes through the interior Tuesday night into Wednesday morning when the best chances for precipitation will occur. The system is not a major system but it will bring some rain and snow to the interior.
A much stronger storm system will be off the Pacific Northwest coast but may spread some showers at times inland over the northern coastal range and southern Cascades Thursday and Friday. Currently that system is forecast to move inland Saturday and Saturday night.
AVIATION.
Overall we will see VFR conditions into the overnight at the terminal sites. BKN clouds 3500 to 5000 feet this evening into the early overnight. We will also see an isolated chance for showers in the valley with showers likely over the mountains. MVFR/IFR in any showers, snow levels 3500-4500 feet. Decreasing clouds overnight with patchy fog developing KMYV south, MVFR/IFR possible between 12-18z. Winds remain under 10 knots.
STO WATCHES/WARNINGS/ADVISORIES. Winter Weather Advisory until 4 AM PST Sunday for West Slope Northern Sierra Nevada-Western Plumas County/Lassen Park.

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. |
