Welcome to PlacefileNation!

May 16, 2022 - 1145CDT: We at Place Nation apologize for being down for nearly a week. GoDaddy had us blocked due to attempts to hack into our system along with all the data we are pushing to the servers. After many hours and several attempts to work with GoDaddy, they magically were able to get our system unblocked and back to normal. This blockage impacted our website where it was completely down, no data transfers were allowed and no placefiles were allowed to be updated.

Placefile Nation was created and is maintained by a team of meteorologists to provide weather data for GR2 and GR3 applications over the United States. Analyzing radar, with reliable data overlays, provides a more seamless, worry-free experience. We know this, which is why we manage and monitor our own data feeds. In an effort to make our site more useful, we appreciate feedback sent to placefilenation@gmail.com.
