I got the word passed down from WSS that in the next few weeks the following sirens are on their way out and replacing with new.
Harper woods - 3 thunderbolts, Probably getting 2001's
Redford - 3 thunderbolts Getting 4 2001's
Northville adding 4 2001's (2 are already put in)and adding a new radio to their thunderbolt
Grosse Pointe area, adding 2001's Except for GP Shores, the other 4 haven't had sirens except back in the 1940's except GP woods's Thunderbolt, which may be going too
No new word on completing Dearborn, Canton, or Detroit at this time.
