A heads-up in the morning.A ping when it lands.
Save the addresses and areas you care about. Hail GPS tells you when hail is forecast for them — and again, within minutes, when a storm actually touches them.
New · The morning heads-up
Know it's a hail day before it fires.
Every morning we check the national hail forecast against your saved territory. If hail is forecast for your area, you get a heads-up by email or phone notification — while there's still time to plan the day around it.
Only when the odds are real.
We gate the heads-up on the forecast probability — nobody gets woken up over a long shot.
Uses the zones you already set.
The same saved addresses and alert areas that drive your storm alerts. Nothing to configure twice.
From the people who forecast severe weather.
The outlook comes from the NWS Storm Prediction Center — we fetch it, map it, and match it to your territory.
Storm alerts
From radar sweep to your pocket, in minutes.
No refreshing the map all afternoon. Set it up once and the storm finds you.
01
Save what you care about
Your customer list, a radius around town, whole states — or the entire country. Set a minimum hail size so small stuff stays quiet.
02
We watch the map around the clock
New hail data lands about every two minutes during a storm, checked against every address and area you've saved.
03
You get pinged when it lands
Email, text, Slack, or a notification on your phone — with the hail size and a link straight to the swath on the map.
Live proof
What just hit.
The public feed — every cell Hail GPS has tracked in the past 24 hours, nationwide, newest first. This is the same data your alerts run on.
Refreshes every 60s
All quiet.
No cells tracked in the past 24 hours. When hail fires anywhere in the country, it streams here.
Put your territory on watch.
Request access, save the addresses and areas you care about, and let the map do the watching.
