What is a Local Tsunami Watch Bulletin (LTWB)?
A Local Tsunami Watch Bulletin (LTWB) is a warning issued by the National Weather Service (NWS) when there is a potential for a tsunami to impact a specific coastal area within the next several hours. It does not mean that a tsunami is imminent or has already occurred.

If an LTWB is issued for your area, you should:
- Move inland to higher ground immediately.
- Do not wait for an official evacuation order.
- Listen to local news for updates and instructions.
- Be prepared for potential power outages, phone disruptions, and road closures.

What is the difference between a Local Tsunami Watch and a Local Tsunami Warning?
