Q: How much does it cost?
A: An annual subscription only costs $4.00 per month. In addition there is a one time $9.95 activation fee to set up your account and to program your information into the ThunderCall system.

Q: How quickly will you call me?
A: Subscriber's telephones begin ringing within 5 seconds after ThunderCall receives the National Weather Service (NWS) warning.

Q: What warnings will I receive?
A: ThunderCalls are made for 5 types of severe weather: Tornado, Flash Flood, Severe Thunderstorm, Hurricane and Winter Storm Warnings. Flash Flood, Tornado and Thunderstorm calls are made once per hour, even if multiple warnings have been issued. Calls for Hurricane and Winter Storm Warnings are delivered between 11:00 AM and 9:00 PM EST and made once every 24 hours. ThunderCalls are only delivered for severe weather WARNINGS. ThunderCalls are not delivered for severe weather WATCHES.

Q: I have a weather radio… why do I need ThunderCall?
A: With ThunderCall there is no equipment to buy, no batteries to replace, and you can receive the alert from any room in your house (with a telephone). ThunderCall can be set up to warn you about severe weather anywhere in the country, not just your local area.

Q: What happens if I am not home or on the telephone when a warning is issued?
A: If you are not home, ThunderCall will leave a message on your answering machine (if you have one) to let you know a warning was issued. If your phone line is busy or if no one is able to answer the phone ThunderCall will make two additional attempts to try to contact you.

Q. How does it work?
A: The National Weather Service (NWS) constantly monitors the weather around the nation. If NWS detects that severe weather is about to occur, it will issue a warning across its satellite system. Our computers constantly monitor these satellites. As soon as they determine that the National Weather Service has issued a warning, we call our subscribers who live in, or who monitor the area that is affected.

Q. Will ThunderCall work on telephone lines with privacy management equipment or services?
A: Most privacy manager services block calls that do not have CallerID information. ThunderCall utilizes dedicated telephone lines for which CallerID is not available and therefore would be blocked if such a service is enabled. Tests with hardware devices, that you install to "fool" telemarketing calls, had no affect on ThunderCall messages. If you are not sure about your particular service, you may email ThunderCall Customer Service at customerservice@thundercall.com and ask for a test call to be placed to your line to ensure full compatibility.
