Real-Time Hazard Maps

Here you will find links to real-time and near real-time hazard maps that will keep you up-to-date on hazardous conditions throughout the Northeast and the US. Please click on the maps to visit the hosting agency's web site. There, you will find additional information and larger versions of the real-time hazard maps.

If you have any questions, please don't hesitate to contact us.

DISCLAIMER: Due to the nature of real-time information, many of these maps are experimental, use provisional or incomplete data, and are subject to significant changes over time. Users should check the accuracy, completeness, and fitness of these maps with the hosting agency before relying on them for mission-critical functions. This is especially important for situations where damage can occur as the result of using provisional or incomplete data. The Northeast States Emergency Consortium is not responsible for any of the maps depicted on this page.
