Shortcuts: type the keys in order to jump straight to one.
NBM is NOAA's National Blend of Models: about 30 forecast models blended and corrected against years of real weather. It's usually the most accurate for a town, so it's the first tab.
Its rain chance is a true chance: 30% means rain about 3 times in 10 days like it. The ECMWF, GFS and RRFS and GFS tabs show each model on its own, and their rain chance is how much of the area around the town that model gives rain.
Feel free to share and use any of these maps, on social media, in a presentation, on air, wherever, at no cost. The one ask: keep the Redwood Weather banner and the data credits in the image. Please don't crop them out or cover them up.
Weather alerts here come straight from the National Weather Service and refresh every minute, but a website can lag or fail to load. Don't rely on this site alone when lives or property are at stake: get alerts from official sources (weather.gov, the emergency alerts on your phone, NOAA Weather Radio) and follow local officials.
Forecasts, observations and river data are shown as received and may contain errors. Everything is provided as is, with no warranty.
Using this site means you agree to the Terms of Use.

Effective November 14, 2026
Redwood Weather ("the site," "we") is a free weather site. By using it, you agree to these terms. If you don't agree, please don't use the site.
The site is an experimental beta. Features, maps and data may change, stop working, or be removed at any time without notice.
The site is not an official source of weather warnings or emergency information and is not a substitute for one. Alerts shown here come from the National Weather Service but may be delayed, incomplete or fail to load. For any decision involving safety, health, life or property, use official sources (weather.gov, Wireless Emergency Alerts, NOAA Weather Radio) and follow the instructions of local officials.
Forecasts are computer model output and estimates, and they are often wrong. Observations, river levels, fire, air quality and other data are shown as received from their sources and may contain errors, gaps or delays. You use all information on the site at your own risk and are solely responsible for any decisions you make with it.
The site and everything on it are provided "as is" and "as available," without warranties of any kind, express or implied, including warranties of accuracy, timeliness, completeness, reliability, merchantability, fitness for a particular purpose, and non-infringement. We don't promise the site will be available, uninterrupted or error-free.
To the fullest extent allowed by law, Redwood Weather and its owner, operators and contributors will not be liable for any direct, indirect, incidental, consequential, special or punitive damages, or any loss of life, injury, property damage, lost profits or lost data, arising from or related to your use of, or inability to use, the site or any information on it, even if advised of the possibility of such damages.
Some places don't allow certain warranty exclusions or liability limits, so some of the above may not apply to you; in that case they apply to the fullest extent allowed.
You agree to hold harmless Redwood Weather and its owner from any claims, losses or costs arising from your use or misuse of the site or your violation of these terms.
Redwood Weather is an independent, personal project. It is not affiliated with, endorsed by, or speaking for any employer, television station, news organization, or government agency, including NOAA and the National Weather Service.
Much of the data comes from government agencies and other third parties, credited on the Info page. We don't control those sources or the outside websites we link to and aren't responsible for their content, accuracy or availability.
You may share the maps, including on social media and on air, as long as the Redwood Weather banner and data credits stay in the image. Don't use the site in a way that harms it or other users, such as automated mass downloading, overloading the server, or trying to break in.
There are no accounts, no ads, and no tracking cookies. Your browser stores a note that you've seen the welcome message. If you send feedback, we keep what you write (and your email, only if you give it) to improve the site and, sometimes, to follow up; we don't promise a reply, and we don't sell or share it. Please don't include sensitive personal information. Like any website, our server and network provider keep standard logs (such as IP address and browser type) for security and to keep the site running. Map backgrounds and some data load directly from other services, which see the same basic information under their own policies.
We may update these terms at any time by posting a new version here. Continuing to use the site after a change means you accept it.
These terms are governed by the laws of the State of California, without regard to its conflict-of-law rules. If any part of these terms is found unenforceable, the rest stays in effect.
