Update (4:45 p.m.):

The National Weather Service says the thunderstorm, which produced hail over northern Steuben and Southern Yates County, has weakened.

Gusty winds and possibly a little small hail may still hit the Ithaca area, but “the threat for more significant impacts with this storm has ended,” the National Weather Service said.

Earlier (4:25 p.m.):

Ithaca, N.Y. — A severe thunderstorm that is capable of producing quarter-size hail may be heading to Ithaca, the National Weather Service says.

The storm may bring winds in excess of 60 mph.

“If you are in the path of this storm … seek shelter indoors and stay away from windows!” a National Weather Service report said.

Here are some recommendations to stay safe during the storm:


  • To begin preparing, you should build an emergency kit and make a family communications plan.
  • Remember the 30/30 Lightning Safety Rule: Go indoors if, after seeing lightning, you cannot count to 30 before hearing thunder. Stay indoors for 30 minutes after hearing the last clap of thunder.
  • Secure outdoor objects that could blow away or cause damage.
  • Get inside a home, building, or hard top automobile (not a convertible). Although you may be injured if lightning strikes your car, you are much safer inside a vehicle than outside.
  • Shutter windows and secure outside doors. If shutters are not available, close window blinds, shades or curtains.

  • Avoid contact with corded phones and devices including those plugged into electric for recharging. Cordless and wireless phones not connected to wall outlets are OK to use.
  • Avoid contact with electrical equipment or cords. Unplug appliances and other electrical items such as computers and turn off air conditioners. Power surges from lightning can cause serious damage.
  • Avoid contact with plumbing. Do not wash your hands, do not take a shower, do not wash dishes, and do not do laundry. Plumbing and bathroom fixtures can conduct electricity.
  • Stay away from windows and doors, and stay off porches.
  • If you are driving, try to safely exit the roadway and park. Stay in the vehicle and turn on the emergency flashers until the heavy rain ends. Avoid touching metal or other surfaces that conduct electricity in and outside the vehicle.
