Clinton County Emergency Alerts Are Becoming More Targeted

For some time, Clinton County Emergency Management Agency has received complaints from residents who were receiving multiple copies of the same weather alert.

We reviewed how subscribers were enrolled and determined that repeated notifications were likely caused by a combination of duplicate registrations, overlapping notification groups, and subscribers selecting several alert options to make sure they received important warnings.

To reduce unnecessary and duplicate messages, Clinton County EMA changed how automated National Weather Service alerts are distributed through Clinton County Emergency Alerts, commonly known as CCEA.

Why Were Some People Receiving Multiple Alerts?

CCEA offered several ways to receive weather notifications because subscribers had different preferences.

Some residents wanted every weather alert issued anywhere in Clinton County, even when their location was not directly threatened. Others wanted alerts only when their home or registered location was within the warned area.

Residents could also register in different ways:

• Some registered online and provided an address.

• Some joined an alert group by texting a keyword.

• Some registered an address and also joined one or more keyword groups.

• Some selected several overlapping weather-alert options.

Residents could choose to receive most weather alerts between 6:00 a.m. and 11:00 p.m., with Tornado Warnings still delivered regardless of the time. Some subscribers also selected additional lists because they were concerned they might otherwise miss a warning.

These options were intended to meet different needs. However, the overlap sometimes resulted in subscribers receiving several copies of the same alert.

How National Weather Service Alerts Work

Automated weather alerts are triggered by the National Weather Service (Storm Based Warnings).

When the National Weather Service issues a warning, it draws a geographic warning polygon around the area considered at risk. These are the outlined areas commonly shown on television and online weather maps.

When a subscriber provides a valid address during CCEA registration, the system geographically locates that address. If the address is inside the National Weather Service warning polygon, the subscriber receives the alert.

If the address is outside the polygon, the subscriber does not receive that particular warning because the National Weather Service has not identified that location as being at risk.

What Changed on July 27?

Beginning at approximately 4:55 p.m. on Monday, July 27, 2026, Clinton County EMA changed the automated weather-alert process to focus on subscribers with geographically registered addresses.

People who had joined only through a keyword and had not provided an address did not receive automated weather alerts after that time.

For example, the National Weather Service issued a Severe Thunderstorm Warning at

6:51 p.m. for only part of Clinton County. The alert was delivered to registered addresses located within the warning polygon.

A person living in Sabina who registered using a Sabina address would not have received that warning because Sabina was outside the warned area. In that situation, not receiving the alert did not mean that the system failed. It meant the registered address was not within the area identified by the National Weather Service as being at risk.

Why Was This Change Made?

Focusing on registered addresses and National Weather Service warning polygons:

• Provides more targeted warnings.

• Reduces duplicate and unnecessary notifications.

• Decreases the total number of messages being transmitted.

• Reduces congestion on cellular and communications systems.

• Makes an alert more likely to represent a threat to the subscriber’s registered location.

This change cannot guarantee that duplicate alerts will never occur. Duplicate registrations, multiple telephone numbers, carrier delays, and other technical issues may occasionally result in repeated notifications.

What You Need to Do

Anyone who previously joined CCEA only by texting a keyword should complete the online registration process and provide a valid address.

Register or update your information at: https://entry.inspironlogistics.com/clinton_oh/wens.cfm

The address is used to determine whether your location is inside a National Weather Service warning polygon.

Current subscribers should also review their information if they:

• Previously joined only through a keyword.

• Have moved.

• Registered with an incomplete or incorrect address.

• Registered more than once.

• Selected multiple overlapping alert groups.

Frequently Asked Questions

Why didn’t I receive a warning?

Your registered address may have been outside the National Weather Service warning polygon. Automated alerts are now more closely targeted to locations identified as being at risk.

You should also confirm that your registration includes a complete and accurate address.

Will keyword-only subscribers continue receiving automated weather alerts?

Keyword-only subscribers who have not provided an address may no longer receive automated geographically targeted weather alerts.

To continue receiving these alerts, complete the online registration and provide a valid address.

Will Tornado Warnings still be sent overnight?

Yes. Tornado Warnings remain an exception to the general 6:00 a.m. to 11:00 p.m. notification period and may be delivered at any hour when a registered address is within the warned area.

Should I delete duplicate registrations?

If a member has concerns, or believes they have duplicate entries and are still receiving duplicate notifications, they should contact the Clinton County EMA office at (937) 382-6673 for assistance.

Does this guarantee I will never receive a duplicate alert?

No. The change is intended to substantially reduce duplicate and unnecessary notifications, but technical issues, carrier delays, multiple registrations, or multiple telephone numbers may still occasionally result in repeated messages.
