    All kinds of weather happening in the #PNW. We have floods, wind, snow - something for everyone.

    NOAA has posted a high wind watch for most of the urban Puget Sound area including Seattle. Possible gusts to 65mph Tuesday night into Wednesday. If you live in this area it would be a good idea to prepare for a power outage.

    For details from NOAA, open the map, click inside any red-outlined area and then follow the link to read the forecast discussion. The screenshot text is from the discussion that covers most of western WA.

    From time to time I will post the following map link which displays all the current weather watches and warnings. Due to changes at NOAA, the map now works in a slightly different way.

    First, here is the part that did not change.

    When you open the map and click a colored area then you see a popup that has a link you can click to see the details of the watch or warning. It is fairly common for there to be more than once active watch and/or warning for the spot that you clicked. When that happens then the popup on your screen will show a separate section for each watch/warning and each section has a link for the details.

    Now the new part.

    When you follow a link then you will see the details for *all* current watches and warning for the spot you clicked. The *first* set of details will be for the type of watch/warning shown in the popup that has the link that you clicked. Hope that makes sense.

    Wish we could send some Redmond WA weather to cool things down in the hot part of the country. Over next 3 days we will have clouds, showers and a high temp in the low 70s.

    When this map opens the basemap is an image from the GOES West satellite.

    Whole Puget Sound area has a wind advisory starting later today. Strongest wind will be tonight.

    For NOAA’s hour-by-hour wind forecast, open the map and rightclick a spot. Look near the top of the sidebar that opens and click "Hourly forecast (USA)". Wind forecast is the second graph.

    Nope, not spring yet.

    #WindChill in the upper midwest reminds me why I do not live there anymore. Snorkel parka anyone? See the screenshot for 'Extreme Cold Warning'.

    And when was the last time you saw a #HighWindWarning for Washington #DC? If only it would blow hard enough to clean out #DictatorTrump and his goons.

    I looked it up. At 5pm #PNW time today the #WindChill at my #Minnesota home town is forecast to be 71 degrees lower than the windchill at our Redmond WA home of many years. 🥶

    Wanna look up the wind chill forecast for somewhere? Open the map and right-click a spot. Look near the top of the sidebar that opens and click "Hourly forecast (USA)". The first graph includes the wind chill forecast. Note the button to advanced the graph for the next few days.

    @mappingsupport I think you're doing good work and I also think #GISsurfer sounds like a pornography sub-genre.

    Each time you open this map you will see the most recent weather watches and warnings. The map covers the USA but is zoomed in on the greater #LosAngeles area when it opens.

    The red area is a #RedFlagWarning.

    NOAA has posted an #IceStormWarning. It is the dark purple area on the map. At the time of my post this is only in SE Missouri. See the screenshot text below.

    Note that other areas are also forecast to have freezing rain but not as much as in the ice storm warning area.

    NOAA has added some new GIS layers related to floods. The symbols on this map are streamgages. Open the map, click a symbol, scroll down and follow the first link. You will see a forecast for water level at that gage.
    Purple = Major flood
    Red = Moderate flood

    The gage in the screenshot is a bit south of Asheville NC

    NOAA has activated their GIS layer that shows the forecast for possible peak storm surge so I added that to the map.

    NOAA’s GIS servers are busy so it might take a few seconds for all the data to appear on the map.
