Doppler storm radar - eMap HDF

Get real-time storm tracking and advanced weather intelligence with Doppler storm radar - eMap HDF, the comprehensive weather intelligence platform powered by NOAA and the National Weather Service.

Stay ahead of severe weather with professional-grade radar and alerts. Track storms, tornadoes, heavy rain, and dangerous wind conditions as they develop. Monitor lightning strikes across your region, access satellite cloud imagery, and receive severe weather notifications before conditions worsen. The app's one-hour rain and snow prediction updates every five minutes, while six-hour NOAA radar history lets you analyze storm patterns and movement with precision.

Explore global weather phenomena with specialized tracking tools. Monitor hurricanes and typhoons worldwide using GDACS data, check earthquake activity filtered by magnitude and depth from USGS sources, and access a complete lightning strike map. Whether you're tracking tropical storms across the Pacific or monitoring seismic activity, you have access to the same data meteorologists rely on.

Plan confidently with extended forecasts and hyperlocal detail. Get 10-day weather predictions and hourly forecasts for the next 24 hours, complete with temperature, precipitation, humidity, wind speed and direction, dew point, visibility, and "feels like" readings. Air quality monitoring shows concentrations of ozone, particulate matter, nitrogen dioxide, and carbon monoxide from multiple authoritative sources including AirNow and Copernicus.

Discover ocean and coastal data at your fingertips. Access tide charts for over 10,000 tidal stations across the US, UK, Canada, and beyond with forecasts spanning several months. Sea temperature data comes from real buoy measurements and satellite observations, helping you understand marine conditions. The app automatically tracks your location and displays tides near you.

Research weather history and plan trips smarter. Long-click any location to view current conditions plus a multi-year weather archive showing sea and air temperature, precipitation, and cloud cover. Compare this year's conditions against historical data to choose optimal travel dates and destinations. View road traffic overlays, check local time in any city, and measure distances between locations in miles or kilometres.

Access unlimited weather layers on a single interactive map. Toggle between 10-day and 24-hour forecast views directly on the map interface. Layer snow and rain radar, satellite imagery, temperature maps, humidity readings, wind patterns, dew point data, buoy locations, and more. All data integrates seamlessly into one intuitive platform.

Doppler storm radar - eMap HDF combines institutional weather data with intuitive design, giving you the situational awareness to make informed decisions about severe weather, travel planning, and daily activities. Note: This app is not intended for maritime navigation.
