EONET (Earth Observatory Natural Event Tracker) is a curated NASA catalogue of natural events that are happening now, each with its location and links to images and sources. Storms come with their track.
Unlike GDACS, EONET does not rate impact. It answers "what is happening where", not "how bad is it for people".
