Gaia GPS NOAA 48 hour precip forecast overlay

Built on Official NOAA Data

The 48 hour precip overlay taps directly into the National Oceanic and Atmospheric Administration (NOAA) forecasting data. The NOAA Weather Prediction Center (WPC) researches and releases short-term forecasts twice daily, based on predictive models and satellite imagery. Their reports can forecast heavy rain, snow, and flash flooding up to seven days in advance.

We’ve limited the forecasting for this map to 48-hours in order to give you the most accurate prediction for weekend trips. The overlay refreshes with new information every 12 hours and currently includes the United States, Canada, and Mexico.

How To Read the Forecast

Known as a Quantitative Precipitation Forecast, the weather overlay shades areas of the map to help you visualize the amount of rainfall during a specified amount of time. 48 hours in this case.

The chart below shows the different shades available depending on the forecast, ranging from 0-20 inches of rainfall. Green and blue shades represent light showers, while darker areas of red or purple indicate larger accumulations.

A Note on Safety

You can use the weather overlay as a planning tool to help you pack, plan your route, and be prepared for the weather ahead. Know the terrain and alternate routes ahead of time, and plan for inclement weather, even if none appears in the forecast. Gaia GPS provides map layers to help plan and prepare but the ‘go’ or ‘no-go’ decision remains with you.
