Vog and wind forecasts

The links below take you to forecasts of vog and wind distribution.

1. UH Manoa Vog Measurement and Prediction project (VMAP)

Volcanic gas and particulate data and forecast. Uses volcanic gas emission rates and wind field data to model and predict the concentration and dispersion pattern of volcanic SO2 and sulfate particles.




2. National Weather Service (NWS) Wind Forecast

Three day forecast for 10 m and transport level (mixing layer) winds, as well as mixing layer height, for SE Hawaiʻi Island including Hawaiʻi Volcanoes National Park.

3. earth

A visualization of global weather conditions forecast by supercomputers, updated every three hours. The link below takes you directly to the SO2 (surface mass) overlay for Hawaii. Overlays for SO4 (SO4ex - sulfate extinction) or PM (DUex - dust extinction) are found by clicking on the 'earth' button, then Mode: Particulates.




4. Windy.com

Wind and weather forecast using multiple input models. Can set up for email alerts based on wind or other weather condtions.
