Response from developer

Hello again, can you send an email to storm@opensnow.com and let us know the exact details? The radar and risk overlays will always refresh with the most recent data, so this behavior is expected. Let us know if it is something other than this. If the issue is fixed, can you update your review to 5 stars or delete this review?
