Experimental EMWIN Browser

This site allows easy web-based access to a full assortment of current products available through the Emergency Managers Weather Information Network (EMWIN). New products are received directly from the NOAA National Telecommunications Gateway and become available here within two minutes of receipt. Available products range from weather observations and buoy reports to tornado warnings and storm reports. If it's text and it passes through EMWIN, it's available here.

This gateway is provided as a free service to the SKYWARN community and our friends and partners.

Data available here does not represent the most recent data available from official channels, nor does it pretend to be a complete repository of available EMWIN data. Data is not always imported into this system in real-time and this system is subject to delays and occasional downtime. Do not rely on this system for mission-critical applications.

EMWIN System Status Information

Real-Time Ingest: Online
Backup Ingest: Offline for 54710004 seconds
Notification Engine: Online

The Real-Time Ingest receives a continuous flow of data from the National Weather Service via a the npemwin software. The backup ingest receives batches of data every two to three minutes from the NWS via an FTP link and operates from the SDF Public Access Unix System. While it's rare for the real-time ingest to go down, there is some additional delay when the backup is the only source of data.

All data is processed via PHP-EMWIN and e-mail subscriptions are available through our Situation Awareness Dashboard.
