Warnings for the facilities and crews you're responsible for.
The NWS warns the region. You're responsible for the courthouse, the public works crew on Route 9, the ball fields, the library and the low-water crossing on Mill Creek. SiteWarn™ monitors each of them individually, 24/7/365, warns your departments about lightning the NWS never will, and gives emergency management days of lead on the ice and flood events that drive closures and pre-staging.
Trusted for 14 years at more than 400 sites in all 50 states, with a 100% client renewal rate.
Customized for a single site — or for a command or operations center monitoring hundreds, even thousands, of sites from one screen.
Why cities, counties and agencies choose SiteWarn
A fully customized program: you set the thresholds, we watch the weather.
Lightning for public works and parks crews
The National Weather Service issues no warning for cloud-to-ground lightning — the hazard your road crews, mowing crews, utility crews, lifeguards and ball-field users face most. We warn each department in time to bring people in, and clear them to go back out.
Facility by facility, crew by crew
An NWS warning is the one thing you already have. We monitor the courthouse, the jail, the offices, the parks and each active work zone individually, so the shelter order goes to the buildings in the storm's path and the rest of county operations keep running.
Flood timing for the crossings you close
Flash-flood warnings for the specific low-water crossings, underpasses and roads you barricade, with expected onset — so public works closes them before the first car goes in, and reopens when the water's actually down.
Days of lead for closures and pre-staging
Ice, heavy snow and large-scale wind events are warned days out — watches up to 7 days ahead, warnings by day 5, with onset and end timing — so you pre-treat roads, stage equipment, open warming centers and make the closure call the day before. Delivered to every department through the portal, app, phone, text, email or API into your mass-notification system.
What a typical city or county program looks like
Every program is built with your emergency manager and department heads. Here is a common starting point for a county; cities and state agencies use the same structure for their facilities and crews.
- Lightning by department: alert on cloud-to-ground strikes within 10 miles of any active work zone, park or pool, warning within 8 miles, all-clear 30 minutes after the last strike — to public works, parks and recreation and facilities.
- Tornado and severe thunderstorm by facility: facility-specific warnings with expected arrival time for the courthouse, jail, offices, libraries and community centers in a storm's path; null-warning notification when the NWS warning does not threaten a given facility.
- Flash flooding by crossing: warnings for named low-water crossings, underpasses and flood-prone roads with expected onset and amounts, plus river-flood outlooks days ahead.
- Winter weather and large-scale events: watches up to 7 days ahead and warnings by day 5 for ice, heavy snow and major wind, with timing for road pre-treatment, equipment staging, warming centers and closures.
- Daily outlook: a morning forecast for the jurisdiction with the day's lightning, severe weather and flood windows, for scheduling outdoor crews and events.
- Delivery: portal and push alerts to emergency management and department heads, live phone call to the on-duty emergency manager for anything life-safety, text and email to crew supervisors and facility managers — and an API feed into your mass-notification or EOC platform.
- Heat (WBGT or heat index): advisories and warnings at your activity or work-rest thresholds on either scale — WBGT by default for outdoor crews and athletics — per site.
- Wildfire: advisory when fire-weather conditions are expected to threaten the site or its access routes; warning when an active fire's location and expected spread put the site at risk, with timing and an all-clear.
- Hazard Matrix for the EOC: your facilities, parks, crossings and work zones grouped by department or district as you define them, with each group's status for every hazard on one grid, for the emergency operations center.

Questions emergency managers and public works directors ask
We already get NWS warnings — what does this add?
The NWS warns your whole region and does not warn on lightning at all. SiteWarn adds facility-by-facility and crew-by-crew warnings with expected arrival time, lightning warnings for outdoor crews and parks, flash-flood timing for the specific crossings you close, null-warning notifications when an NWS warning doesn't reach a given facility, and a meteorologist you can call.
How far ahead do you warn on winter weather?
Ice, heavy snow and large-scale wind events are issued as watches up to 7 days ahead and converted to warnings by 5 days out, with onset and end timing, so road pre-treatment, staging and closure decisions can be made the day before.
Can one program cover every department and facility?
Yes. Jurisdiction programs cover every facility, park, pool and work zone with per-location thresholds and contacts on a group rate, with unlimited users across departments. Single-site programs start at $99.95 a month; multi-site discounts apply — ten sites does not cost ten times one.
Is this available through cooperative purchasing or a government contract?
Contact us. We work with cities, counties and state agencies on the procurement vehicle that fits, including cooperative purchasing agreements where available.
What does the Free Live Trial involve?
We set up your real facilities, crews and crossings, thresholds and delivery methods and monitor them exactly as we would for a paying client — no credit card and no obligation. Most sites are live the same day; overnight requests are set up the next morning.
