Big Bend Weather Forecasts

Our Forecasts section provides the most recent "Point" forecasts, regional predictions for the probability of rain, lightning, storm fronts and more. Forecasting is difficult as it is subject to thousands of variables which are constantly changing by the second. Additionally, the Big Bend is well known by the meteorology community as a micro-climate that breaks all the rules for conventional forecasting. We utilize data generated from the National Weather Service’s National Digital Forecast Database (NDFD) combined with data from our instruments along with our onsite human observations, to give you the most reliable and accurate forecasts for the region.

Our 5 day Point forecasts display graphical, summary and verbose versions for a number of communities and locales in the Big Bend. We have combined our various forecasts in a single page display, with a drop down arrow to easily select any of 13 different locations (including several locations in Big Bend National Park). A printer icon in the lower right of the page links to a "printer friendly" version of any forecast.

Of special attention: Any time you are on the Big Bend Weather site, by simply hovering your mouse or (pointing device) over "Storm Lab" on the main menu, you will see at a glance whether or not there are any currently issued advisories for Brewster County.

Our Warnings section of Storm Lab provides users with a convenient location to quickly access both Hazardous Outlook bulletins for the region and Brewster Cnty Advisories issued by the National Weather Service. Out site polls the NWS database for any issued warnings or any type of severe weather advisories and makes them readily available in an easy to access location.

In our  Fire Weather section, users can view a 7-Day Significant Fire Potential Map for the Big Bend with the option to view other geographical areas of the nation.

The Hydrology section of Big Bend Weather provides alerts and flood warnings along with flow and depths of the Rio Grande for 10 USGS gauging stations along, upstream and downstream of the park boundary.
