Severe-weather decision support for county emergency management
When a warning hits, the question isn't “what does the radar show” — it's who and what is in the path, and what do I do about it. Atmostorm turns a live NWS warning polygon into the residents and critical facilities inside it — the decision-support layer small and rural agencies most lack and can't afford an enterprise suite for. Free, self-serve, no GIS staff required.
What you get, free
Who & what is in the warned path
Every active warning for your county, with the estimated residents and the hospitals, nursing homes, mobile-home parks, schools, and dialysis centers inside the polygon.
County activation briefing
A one-tap, print- or PDF-ready EOC briefing at the start of an activation — the situational map, county-wide impact, and a per-warning breakdown you can forward up the chain.
Surveyed damage tracks
After the storm, the official NWS Damage Assessment Toolkit tracks and EF ratings, matched to your county for after-action review.
Live emergency-mode map
Alerts, radar, critical facilities, and damage tracks on one map, tuned for decisions over diagnostics.

Help shape what we build next
We're designing tools for small & rural county EM — including a shared map where a team can mark homes/businesses safe or needs-help during a response. Tell us how you work today and what would actually help. Free early access for pilots.
Questions
Is it free?
Yes. The impact view, the county activation briefing, and the surveyed-damage layer are free and self-serve. We're validating paid workflow tools (like collaborative field canvassing) separately — the core decision-support layer stays free.
How is this different from IPAWS, Everbridge, or WebEOC?
We're not a mass-notification or incident-management platform and we don't originate alerts — those are enterprise tools with big budgets and setup. Atmostorm is the interpretation layer on top of public NWS data: it turns a warning polygon into 'who and what is in the path' — the decision-support piece small and rural agencies most lack and can't afford.
Do I need GIS staff or special software?
No. It runs in a browser, self-serve. There's nothing to install and no ArcGIS license required — that's the point for a one- or two-person agency.
What data does it use?
Public data only: live NWS/SPC warnings, census population, and public critical-facility datasets (hospitals, nursing homes, schools, mobile-home parks, dialysis centers), plus NWS Damage Assessment Toolkit survey tracks. It's decision support, not an authoritative alert source — always confirm with your local NWS office.
Can my whole team use it during a response?
The impact view and briefing are shareable today. A collaborative field map — where a team marks homes and businesses safe or needs-help as they canvass, synced across everyone — is what we're designing next, and pilots get free early access. Tell us how you work below.
Decision-support only — not an official warning source. Always confirm with your local NWS office and follow official guidance. Population and facility figures are estimates from public data.
