Chris, Current protocol for Michigan's Emergency Alert System requires all sirens to go off for the entire county, if the county is named as a place where severe weather is occurring (or is likely to occur). New protocols are in the works, but will not go in place for a while. These new protocols will divide each county into 9 sections (North/East, North, North/West, Mid/East, Middle, Mid/West, South/East, South, South/West), and will allow for targeted notifications. The current system has been in deployment for a very long time and was based on an entire county getting notified (this was as close as the weather systems were able to identify at the time). Newer technology is in the works... -Nick -----Original Message----- From: Chris Wolf [mailto:[log in to unmask]] Sent: Tuesday, April 06, 2010 2:23 PM To: [log in to unmask] Subject: Re: [MSUNAG] Emergency Warning Anecdote I received the warning email message at 12:06, 33 minutes after it was sent, and the all-clear email at 12:10, 20 minutes after it was sent. Is there anyone who received the warning before it expired (at 11:45 for the southern Ingham County part, the closest warning area to us). One odd thing about the emails and the siren is that Lansing, East Lansing, the MSU campus, etc. were not even part of the area for which the warning was issued. I guess whoever manages the siren and the alert system is just being cautious. However, couldn't the email system include the actual text of the National Weather Service warning, so recipients could read the details for themselves? -----Original Message----- From: Gene Willacker [mailto:[log in to unmask]] Sent: Tuesday, April 06, 2010 12:31 PM To: [log in to unmask] Subject: [MSUNAG] Emergency Warning Anecdote I just received my e-mail notice about the tornado warning. Based on these headers, it looks as though it may have been in the msu.edu mail queue for about 45 minutes. Anyone else have stories about the emergency alert systems? This would be a good time for DPPS and others to collect data. Co-workers here were getting phone and SMS alerts after the storm had reached Webberville and the sirens were turned off.
