Although I'm not in CT, here's what I found over the last two weeks in my area.
Two weeks ago (June 27th & 28th) in the Binghamton, NY area there was severe flooding and cleanup is still going on. Thousands of homes were destroyed and a major highway and bridges were washed away.
I kept more than 20 scanners running and they were all very busy.
Some of the news articles and photos are here:

Here are some the groups/frequencies that were very active in addition to the typical PD, Fire, and EMS frequencies. I'm sure I've forgotten to include a few.
I'll try to keep it brief. If you have any questions, I'll be glad to add to this.
Some of these frequencies were rarely active prior to this.
Local Gas & Electric companies - Power lines were down and gas lines were washed out.
USCG Search & Rescue - I'm far from what I would consider 'normal' CG turf but they were quite active.
The local hospital security and paging frequencies. One hospital was flooded and they had to evacuate everyone to the other two hospitals in the area. Just today they are starting to move people back.
Army National Guard
Emergency Management
County EMA
State EMA
Federal EMA (FEMA)
American Red Cross - The national frequencies weren't very active but the local repeater was.
F1 Red Primary - 47.420
F2 Black Secondary - 47.500
F3 Tan Alternate - 47.460
F4 Yellow Backup - 47.660
F5 Orange Tac-1 - 47.540
F6 Blue Tac-2 - 47.620
F7 Purple Tac-3 - 47.580
Vestal,NY - WQDR808 - 453.200
Air & airport Frequencies:
Helicopters - 123.050 mhz - Lots of chatter
Airport Security
Medevac 155.265 (in this area)
All of the helicopters were active on the following local airport frequencies.
Tower
Approach 0-5000'
Clearance
Sate Police helicopters
FRS & GMRS - Very active, including rescue activities. More than I would have expected.
Salvation Army
Hams
CB Radio - Some communications within neighborhoods.
These were all very active and still are almost two weeks later. I normally consider these to be pretty boring. They've been very interesting lately.
Local Government
Local Departments of Public Works
Local Highway departments
