How many lightning strikes hit Texas yesterday?
51,549 lightning flashes were detected across Texas on Tuesday, September 29, 2026, local time. Activity peaked at 7 PM CDT with 11,721 flashes in a single hour — about a normal day for this state.
Counts come from the NOAA GOES East/West Geostationary Lightning Mappers, which detect optical flashes from orbit. They include in-cloud lightning and are not a confirmed cloud-to-ground strike tally. A day here is a local calendar day in America/Chicago, and totals are aggregated over the Texas bounding box, so cells near a border can fall either side. No detections in a period is not an all-clear.

Questions about Texas daily lightning counts
How many lightning strikes did Texas have yesterday?
NOAA GOES East/West GLM detected 51,549 lightning flashes across Texas on Tuesday, September 29, 2026, local time. Activity peaked at 7 PM CDT with 11,721 flashes in that hour. These are satellite-detected optical flashes, not a confirmed cloud-to-ground strike count.
What counts as a day on this page?
A local calendar day in Texas (America/Chicago), midnight to midnight — not a UTC day. An evening storm that runs past midnight UTC still counts toward the evening it started.
Is this the same as the number on the Texas lightning map?
No. The map page counts a rolling 24-hour window that moves with the clock. This page counts closed calendar days, so the totals are answering different questions and will not match.
Are these cloud-to-ground strikes?
No. GLM is an optical instrument on a geostationary satellite and detects total lightning, which includes in-cloud flashes. Counts are flash detections, not confirmed ground strikes, and locations are approximate flash centroids.
