Update 7 p.m. — 

From Tompkins County Public Information Officer Marcia Lynch:

“Route 89/Taughannock Boulevard near the State Park and Route 34/East Shore Drive in Lansing are temporarily closed due to excessive rain run-off and several trees and wires down” …

Northern areas of the county (Ulysses and Lansing) experienced heavy rainfall and some winds in a short period of time; other areas report little activity beyond flooded basements and ditches running over some roadways.

Responders advise caution in driving—watch for water over the roads and the potential of falling trees as the rain soaked grounds loosen tree roots.

Update 6 p.m. —

The number of customers losing power during Tuesday’s thunderstorm in Tompkins County has increased to 1,514, according to NYSEG.

That number was as of 5:45 p.m., NYSEG reported. Of those customers, the vast majority were from Ulysses. The small town, population 4,900, had seen 1,095 power outages.

Also facing power outages were: 48 people in the town of Ithaca; 217 in Enfield; 8 in Dryden; 17 in Lansing; and 129 in Trumansburg.

Update 5:30 p.m. — 

Drivers should stay away from East Shore Drive and Taughannock Boulevard as much as possible Tuesday afternoon, according to emergency officials.

The Tompkins County 911 Dispatch Center said Tuesday that heavy flooding and downed trees have hit those roads hard. NYSEG and the highway department have been called to try and take care of the problem.

“There’s other flooding on side streets, but we’d like people to stay away” from East Shore Drive and Taughannock Boulevard, an official with the 911 center said.

Update 5 p.m. — 

Firefighters in Newfield say they’ve seen hail but only been called to one report: of flooding in the basement.

Firefighters hadn’t heard of downed trees or wires in the town. On Facebook, several users reported “hail measuring 1.75 to 2 inches” in Newfield.
