Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
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.

Showers and thunderstorms are forming this afternoon mainly south of Highway 50; these will spread northward into the evening. Additional chances of showers and thunderstorms can be expected each afternoon at least through the middle of next week. Hot temperatures are forecast for the weekend and next week. Heat impacts are possible for sensitive groups and those with limited cooling options for their homes.
No major changes to the central messages that temperatures will be climbing as high pressure build over the region and daily chances of afternoon thunderstorms will be present at least through the middle of next week.
High pressure continues to strengthen across the Southwest with model forecasts showing close to 600 decameters at the 500 mb level. This correlates to hotter conditions with afternoon highs in the upper 90s to low 100s for western Nevada and upper 80s to around 90 in Sierra valleys. Additionally, temperatures are not expected to efficiently cool each night; lows are generally forecast in the upper 60s to 70 degrees for western Nevada and mid/upper 50s in the Sierra. These conditions could cause issues for those working long hours outdoors or for sensitive populations. Know the signs of heat illness.
Thunderstorms will be the other pervasive feature for the forecast. Moisture streaming around the western periphery of the high will support daily thunderstorm chances mainly for the Sierra and Sierra Front. However, some models are showing periods of enhancement for days where troughs pass close to the region. Sunday/Monday is one period where thunderstorm coverage/intensity could be higher. With PWATs increasing, storms will become wetter as we move through the weekend into early next week. Still, lightning strikes outside of storms cores will be capable of producing new fire starts. Please remember to report any smoke you see.
With the trough passing close to the region Sunday/Monday, winds will kick up a little and could cause Fire Weather concerns mainly for wind prone locations towards the Oregon border. Otherwise, expect typical wind gusts to around 20-25 mph each afternoon as the zephyr forms.
As for a pattern change, models have slipped 24 hrs later than yesterday for the approach of a larger trough along the Canadian/Pac NW coast. This is fairly typical when strong weather features are present; models tend to push change too quickly. A likely scenario would be for strong high pressure to persist into the end of next week before the strong Gulf of Alaska trough shifts into the Canadian Pacific coast and Pac NW. Whenever the trough does begin to shift inland, we'll likely see afternoon wind enhancements and increased fire weather concerns. Boyd
Forecast is on track this afternoon and evening for the development of showers and thunderstorms along the Sierra from as far north as Portola south into Mono County and extending out into the Sierra Front region.
Chances/Timing for terminals to be impacted by thunderstorms today are as follows:
KRNO: 20-25%/23-03Z KCXP/KMEV: 25-30%/22-03Z KTVL: 20-25%/23-03Z KTRK: 20-25%/22-03Z KMMH: 25-30%/22-03Z
Mountain obscuration, lowering CIGS/VIS, and erratic outflow winds are possible in the vicinity of showers with the threat of small hail, lightning, and brief downpours from any thunderstorms that form during this time.
The thunderstorm pattern continues for the weekend into next week with isolated to scattered chances possible for all area terminals. With high pressure strengthening over the region this weekend, daily temperatures will be quite warm region-wide lasting into next week. As a result, thermal turbulence is possible for our western Nevada sites with turbulence and density altitude issues for Sierra terminals. -LaGuardia

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.
