Weather is a frequent topic in the mountains.   This page is about places to get information about weather.  To read general info, please check out our weather page.  

This page is about knowing it will rain so much that trees will fall over and power will go out. Or if it will be windy and we're under a Red Flag warning. Or if it will snow. Or just how much rain fell in that last storm. Whatever the need, there are lots of weather websites to help answer the questions. This list presents a bunch of them - recommended by the 95033talk users - that focus on (or can be made to focus on) our area.

  • NOAA - Possibly the best, very local forecast available is at the NOAA site.  This link is a forecast for the area at the intersection of 17 and Summit Road. Drag and click in the map halfway down on the right side of the page to select the location you are interested in. You'll get a pinpoint forecast for that area by doing so. We've had pilots on the list say they like this site.  Note: the NOAA site is very deep, with lots of data available. The longer you dig around in it, the more you will find.  All the special weather alerts - wind, rain, snow, red flag, and other warnings - that affect you are available via your pinpoint forecast site.
  • Wunderground is a detailed weather site that accepts data from local weather stations.  It shows all kinds of weather and other data, with automated updates. Zoom in to find your neighbors who share their data, and click on any listed site to see the local details.  You can dig in and find historical data at each site as well.   Some useful links:

There are dozens of personal weather stations in the area. Vast majority are on Weather Underground. The rainfall amounts vary substantially over the area - based on terrain, the draw etc. Best if you find a weather station near you; which you can do by clicking on this link, then zoom in and in the layers (on the right) click on Weather Station and precipitation.

Note - the stations for this area will all be KCALOSGAXXX. 

The "K" in the desiganation means it's a Personal Weather Station. CA is state LOSGA is city XX or XXX will be the unique number of the PWS Local weather stations that our neighbors have shared in the 95033Talk area:

Local weather history data online in other ways. 

  • http://www.brushroad.com/ - rainfall chart on Brush Road (maintained by Michael Mc)
  • http://goo.gl/eZWBCk - daily rainfall amounts on Miller Hill, going back to the 2011/12 rainyear, plus charts in other tabs that show the comparison of rainfall over time (maintained by Brian H)

Other sources for weather data:

  • Twitter - The twitter feed from the National Weather Service that covers our area. They regularly share maps showing rain predictions and totals, and other weather data. You don't need a twitter account to see this... just click on the link. Very useful data, and they often reply to tweets asking questions as well. These are the folks that provide the data in the NOAA website in the first link on this page.
  • Weatherwest.com - A blog full of detailed, well written, up to date information about California weather. If you have an RSS reader, you might consider adding this site to it.
  • Nullschool.net - Probably the most beautiful map of wind data available anywhere. You can change the altitude you're looking at, as well as look both backward and forward in time to see what the winds will be doing. The link above is set to show the jet stream and the pacific ocean.  You can click & drag on the map to change the view to anywhere on the planet, as well as zoom in & out with your mouse wheel. Just looking at this map is mesmerizing.
  • Audio from local NWS Weather Radio KEC49 (162.550MHz) from Mount Umunhum, including timely non-weather All Hazards Warnings.
  • US Drought Monitor. Detailed maps of the US with information on drought conditions over the entire country. You can zoom in to any state and get details.
  • Drought monitor map for California
  • Bay area reservoir water levels
  • A very pretty website with simple forecast data. Great radar animations
  • ABC Local KGO - Zoomable weather radar maps with nice animations
  • Accuweather - Another site with zoomable weather radar and animations
  • Weather.com - A basic forecast and data, with a static radar map. I mostly include this because they provide a 10 day forecast as well.  They even have a monthly forecast available too, but we all know that weather predictions more than a couple of hours out are of dubious value. If you're trying to plan something, they might help, but use at your own risk.
