Flood watches and advisories are posted for the entire state into Friday in some cases and into Saturday in others.
Towns that were hit hardest by flooding earlier in the week have been preparing for this storm.
In Southbury, firefighters met last night to get their equipment together, including pumps, boats, cots, tarps and generators.
In New Milford, town officials hope they can keep the roads as clear as possible once the rain starts again. Getting around has been difficult because many roads are still impassable after Monday's flooding.
"The hardest part is trying to get them to fix it. It normally takes them a day or two to fix it after something like that happens." John Jaskolka, of New Milford, said.
The mayor said money is extremely tight and hopes the town will qualify for federal dollars.
At the Stevenson Dam, the Housatonic River's high water levels can't go down fast enough.
“With all the water -- in Danbury got (we’ve got 4 ½ inches of rain -- so its gotta come down,” Ron Prajer, the assistant chief of Oxford’s Fire Department, said.
Water has caused damage down Route 34.
When Eric Roberstad returned to his Oxford home, he found his Jeep Wrangler wrapped around a tree.
“I've got water lapping up against the side wall, porches and whatnot. Once I get in there, I can see if I have damage on the floor,” he said.
Oxford town officials are continuing to keep homeowners up to date on the river levels through a reverse 911 system.
