Reading the radar

  • Blue→green→yellow→red = light → heavy precipitation. Green already means small-craft weather is building; red means get off the water.
  • Drag the slider past “now” for RainViewer’s nowcast — a 30-minute radar extrapolation, handy for timing a last reach before the cell arrives.
  • Radar is precipitation only: it will not show the clear-air gust fronts that precede thunderstorms. Combine with the hourly forecast rain-probability column.

Water level data comes from the USGS gauge above; wind is modeled for the lake’s coordinates by Open-Meteo. Always confirm conditions locally before launching — shorelines, ramps, and trees can all change what you feel on the water. In the Southwest, wind is a terrain story: desert basins run strongest in spring afternoons, canyon mouths funnel gusts far out onto the water, and monsoon storms can build fast after midday in summer. Mornings are the calm, predictable window.
