Lightning strikes in Montana yesterday → Closed-day count with the last week of daily totals.
Data sourced from NOAA GOES East/West Geostationary Lightning Mappers (GLM) and the Storm Prediction Center (SPC). For the broader live overview, open the lightning strike map for the last 24 hours, or switch to Montana lightning radar when you want storm structure alongside the strike detections.
What the counter, heatmap, and map above are actually showing you
The counter at the top of this page reports flashes detected across Montana in the last 24 hours from NOAA GOES East/West GLM. It updates throughout the day; provider and display cadence and latency vary. It counts satellite-detected optical flashes, so it is not a cloud-to-ground strike tally.
The heatmap renders the same 24-hour window as glow density, so you can see which part ofMontana carried the activity. Open the live map for individual flash markers and timestamps, then a Billings city page for local detail.
The national last-24-hours map has a 12H / 24H control for a tighter recent window and covers every state at once. For the distance to the single nearest recent flash, use the closest-strike checker. To check whether a Montana storm is producing lightning right now, open thethunder tracker. For closed days instead of a rolling window, see how many strikes Montana had yesterday.
Recent GLM activity on this page is not historical state climatology. It shows a rolling detection window, with sensor coverage, provider processing, and map refresh limits.
For carefully scoped long-term context, read most lightning-prone states; for source and coverage limits, read the methodology. Do not use a quiet live map as a seasonal ranking or safety signal.
Recent GLM detections within a state are not a historical thunderstorm climatology. Use the live map for current context, then consult the source-scoped state guide and methodology before comparing places or periods.

Monitor lightning activity in these Montana cities
Know where to shelter and follow official warnings when storms approach Montana
Any audible thunder means lightning can reach you, so go inside without counting seconds. Stay indoors for 30 minutes after the last thunderclap.
Have a shelter plan before storms reach Montana. Avoid windows and stay away from plumbing while indoors.
Use Lightning Tracker for supplemental situational awareness near Montana. Follow official warnings and seek shelter immediately when thunder is audible.
If caught outside, avoid open fields, hilltops, and isolated trees. Seek shelter in a substantial building or hard-topped vehicle.

This page shows recent NOAA GOES East/West GLM optical-flash detections across Montana. Use official weather agencies for forecasts and warnings.
The live counter on this page reports flashes detected across Montana in the last 24 hours by NOAA GOES East/West GLM. It refreshes throughout the day; provider and display cadence and latency vary. These are satellite-detected optical flashes, not a confirmed cloud-to-ground strike count, and the 24-hour heatmap shows where in Montana that activity fell.
The 30-30 rule is older guidance: shelter if the count from flash to thunder is 30 seconds or less, then stay indoors 30 minutes after the last thunderclap. The National Weather Service now uses a simpler trigger: when thunder roars, go indoors, because any audible thunder means lightning can reach you. The 30-minute wait after the last thunder still applies.
Lightning Tracker uses NOAA GOES East/West GLM (Geostationary Lightning Mapper) satellite data to display recent lightning activity across Montana. Premium can send push notification alerts for qualifying activity near a saved area; maps remain supplemental to official warnings.
Download the mobile app for live alerts, then use the Montana hub, city pages, and lightning guides for local map and safety context.
