The city and county have implemented the NacWise alert system to notify everyone of emergencies. Even if you were on the previous system you will still need to sign up. You can go to the homepage for the city of Nacogdoches, or go directly to https://signup.hyper-reach.com/hyper_reach/sign_up_page_2/?id=106044. It’s fairly straightforward and provides you with alternative methods for being contacted.
If you are part of a neighborhood association or other group I hope you will share this link and encourage your family and friends to also register for emergency notifications.
