Linn County events only
Local EOC report view. Shows only items that appear to match the selected county using county name, UGC, SAME/FIPS-style identifiers, and known local terms where available.
Iowa events only
Statewide relevance view. Shows Iowa-related items from the Iowa-serving WFO feeds. This may include items outside the selected county, but still relevant to Iowa situational awareness.
Raw WFO/IEMBot feed
Wide-open feed review. Shows the merged WFO/IEMBot feed from the Iowa-serving offices. This can include neighboring-state items from ARX, OAX, FSD, or DVN because those WFOs cross state lines.
