Alabama SAF-T-Net

How It Works

Precision Weather Alerting

Continuously monitored by a staff of degreed meteorologists, advanced computer processing analyzes the weather 24/7, searching for dangerous conditions such as strong winds, hail and tornadoes. When severe weather activity is detected in one of your selected alert locations or your current location, Alabama SAF-T-Net dispatches a notification to your mobile device through an easy-to-use app. You only receive an alert when a location is under threat from by hail, high winds or potential tornadoes.

 

Following are the types of alerts you can opt to receive with Alabama SAF-T-Net:

National Weather Service (NWS) Storm-Based Warnings

Storm-based, or “polygon”, warnings are typically issued from the National Weather Service office nearest you. They are more targeted and location-specific than traditional county-wide warnings. Alabama SAF-T-Net notifies you of the following types of storm-based warnings:

  • Tornado Warnings: The National Weather Service issues a Tornado Warning when a tornado is indicated by radar, or reported by spotters. You should seek shelter immediately if Alabama SAF-T-Net notifies you that a Tornado Warning has been issued.
  • Severe Thunderstorm Warnings: A Severe Thunderstorm Warning is issued when a storm producing hail one inch in diameter or larger and/or winds equal to or exceeding 58 mph is detected. Severe thunderstorms can cause structural damage and produce tornadoes with little to no advance notice, so seek shelter if a warning is issued.
  • Flash Flood Warnings: This type of warning is issued when a flash flood is imminent or occurring in the warned area.

If you receive an Alabama SAF-T-Net notification for a storm-based warning, be prepared to take action.

Notifications for weather near your location

The exclusive technology at work in Alabama SAF-T-Net constantly scans your area, looking for developing weather threats. If a severe storm cell is identified—a hail-producing thunderstorm, for example—the system instantly and automatically dispatches a notification to you (login to your account to opt-in for these messages). These types of alerts encompass weather activity ranging from dangerous storms to specific alerts for hail, rain, snow, and wintry mixes.

 

Dangerous storm notifications

The text for this type of message will look like this: SAF-T-Net Weather Alert: Dangerous storm approaching your (location), followed by the storm’s Baron Tornado Index rating.

When you receive a “dangerous storm” message from Alabama SAF-T-Net, it means that a storm capable of these characteristics will be arriving at your registered location(s) within 15 minutes:

  • Hail
  • High, damaging winds
  • Flooding rains

Twisting storm notifications

The text for this type of message will look like this: SAF-T-Net Weather Alert: Twisting storm approaching your (location), followed by the storm’s Baron Tornado Index rating.

When you receive an Alabama SAF-T-Net message indicating a dangerous twisting storm is approaching your location(s), it means that a storm containing wind shear, a prime indicator of tornadoes, will be arriving at your registered location(s) within 15 minutes. In addition, you will receive a Baron Tornado Index (BTI) ranking on the likelihood of an actual tornado developing.

The Baron Tornado Index®

The Baron Tornado Index®, or BTI®, provides a simplified 1-10 ranking on the likelihood of a tornado within the storm.

Using sophisticated computer modeling, the patented and patent-pending BTI has proven remarkably successful at the prediction of tornadic supercells, beginning with the Super Tuesday outbreak of February, 2008. Combined with the localized power of SAF-T-Net, the result is accurate, targeted weather awareness that’s available nowhere else.

Custom messages from local EMA officials

During severe weather, participating Emergency Management officials can send you customized messages with specific information or safety instructions, providing a personalized supplement to Alabama SAF-T-Net’s notifications.
