IEM VTEC Product Browser

This application allows easy navigation of National Weather Service issued products with Valid Time Event Coding (VTEC).

1. 13 June 2025 Update: As a part of a broader IEM website update, this tool was rewritten. Please let me know of any bugs.
2. 13 Nov 2024 Update: The tool was updated to use non-hash link style URLs. A shim is in place to translate the old URLs to the new ones, so nothing should be broken (famous last words). This was done to allow the HTML5 History API to provide a better user experience.
