To get Guadalupe County emergency alerts on a mobile device or by email, register your contact information and each address of interest through the county's Regional Emergency Alert Network page, then activate the registration from the confirmation email.
The county describes REAN as a way for local officials to send instructions during significant emergencies, including floods, tornadoes and hazardous-material spills.

Once you have registered, a confirmation e-mail will be sent to your primary email account.Guadalupe County Office of Emergency Management ↗
Residents with a Guadalupe County home, work or school address can register that address for area-specific emergency messages, including residents in cities such as Seguin, Schertz and Cibolo. The county says the network covers Guadalupe, Comal and Bexar counties and allows a separate registration for each address of interest in that area. The address matters: it tells the network which area's notifications you have asked to receive.
How to sign up
Start at the county's REAN page and use its Guadalupe County signup link. Enter the contact information for the devices or email accounts you want to register. The county says the system accepts cell phones, pagers and email accounts; its page also describes messages to registered standard voice and text devices. Add the address for which you want alerts, then repeat the registration for another qualifying home, workplace, school or relative's home if you want notifications for that area too.
