Lightning alerts before thunder sounds

TLN lightning safety solutions provide best-practice decision support as defined by the American Meteorological Society. Receive a world-class lightning safety solution through direct alerts, a customizable visual display system, and a local Tempest lightning sensor deployed at your location.

  • Immediate SMS and email alerts
  • Configure alerts for multiple recipients, schedules, and locations
  • Custom all-clear notification
  • Map of strike locations

Build with the Tempest Lightning Network API

Real-time lightning data can be added to your existing platform or custom app. Our developer-friendly data stream sends lightning strike data in real-time.

  • Integrate the same quality data used at TLN
  • Data provided in common delivery formats
  • Distinguishes between cloud-to-ground and inter/intra-cloud lightning events
  • Includes the intensity and polarity of each strike, as well as location

Historical Lightning Data

Tap into TLN’s enormous database of historic lightning strike verification data.

  • Search 24, 48, or 72 hours from a given date/time
  • Search one, five, 10, or 15-mile radius from a given location
  • View a list of strikes and each strike’s distance from the specified location
  • Download a customized PDF report and data files in KML and CSV formats
  • Long-term data for research is also available

A Turnkey Lightning Safety Solution

  • Self-install a TempestOne Weather Station on-site for enhanced local lightning detection
  • Access data on the TempestOne web app or Google Earth display
  • Audible and SMS/email alerts
  • Alerts for multiple ranges upon initial lightning strike
  • All clear notifications based on a custom preset period
  • Rainfall start time, end time, and other alerts are available

Become a Channel Partner

When lightning strikes, be the first source for alerts. TLN’s pricing model is business-friendly for app developers and resellers who want to integrate lightning detection data within end-user solutions. Data is available via API for web or mobile app integration; the perfect customizable add-on for weather and safety offerings; or it can be viewed using the TLN display. Alerting and a historical lightning data archive API are also available, along with custom lightning verification reports. Not a developer? We offer turnkey solutions for accessing real-time lightning data — from visual display systems to email and SMS alerting services.

TLN employs local and industrial-grade regional sensors to ensure superior detection capability.

Industrial-Grade Sensor

The LPS-200 advanced lightning sensor with digital signal processing is designed to deliver the latest in precision detection. Leveraging LF/VHF dual-band operation, the sensor processes lightning strikes from cloud-to-ground and cloud-to-cloud lightning simultaneously.

Using a high sensitivity, low noise wide-band receiver, state-of-the-art digital filters, and precision GPS time reference, sensors characterize and categorize each strike the instant it occurs.

  • Captures over 95% of all cloud-to-ground strikes
  • Geo-location precision to <100m
  • Differentiates positively charged strokes/strikes vs negatively charged
  • Uses patented time of arrival capability to determine the location of strikes

Local Area Sensor

TempestOne Weather Stations include a sensitive RF receiver that detects the environmental electrical emissions from lightning activity up to 40km away while rejecting disturbances from man-made signals. This advanced warning capability alerts users so that precautions can be taken.

  • Detection of both cloud-to-ground and cloud-to-cloud lightning activity within a 40km range
  • Intelligent algorithm provides false detection rejection
  • Antenna auto-tuning
  • Works in conjunction with patented time of arrival capability to determine the location of strikes
