A severe thunderstorm warning has been issued for Northern Genesee County.

At 3:12 p.m. the National Weather Service office in Buffalo issued the warning, saying the severe thunderstorm was located near Middleport, or seven miles west of Medina, moving east at 35 mph.

The storms may intensify and torrential rains are possible, which could cause localized flooding.

Winds in excess of 30 mph are expected.

There is a hazardous weather outlook in effect for Genesee County.

The National Weather Service says showers and thunderstorms today will increase in number with a marginal risk for strong to severe thunderstorms by late afternoon. Damaging wind gusts is the primary threat, with isolated large hail also possible.

Because of this outlook, tonight's free concert by the Batavia Concert Band at Centennial Park has been moved to Stuart Steiner Theatre at Genesee Community College. It will also feature a student alumni musical tribute to the late Batavia school band instructor Neil Hartwick.

Press release:

Due to high energy demand caused by this week’s extreme heat and humidity, National Grid is asking Upstate New York customers to reduce unnecessary electricity usage for the remainder of the week. Electricity supply to the area is adequate, but continued heavy demand and high temperatures could pose a threat to network reliability.

The company recommends a few simple customer actions to help reduce demand on utility equipment and maintain system reliability. These small actions, combined with those of your neighbors, can make a big difference -- and they can help you better manage your energy bill.

  Draw blinds, shades, drapes to prevent the sun from making your home too hot.

  Slightly increase air conditioner settings, change the filter, use fans – The lower your air conditioner temperature, the more costly it is to operate. For example, a 75-degree setting will cost about 18 percent more than a 78-degree setting. Set the thermostat as high as comfort will permit. In addition, check your window air conditioner filter and replace or clean it if necessary. If your home has central air conditioning, check the condition of the furnace filter and replace it if dirty. Using fans instead of air conditioning also reduces energy usage.

  Consider a programmable thermostat – You could save up to $180 annually by adjusting cooling temperatures when rooms are unoccupied.

  Turn off lights when they are not needed.

  Delay the use of hot water appliances like dishwashers and washing machines.

  Unplug electronics – Even though your electronics, like televisions and computers, are turned off they may still draw electricity. Unplug any unnecessary electronics and chargers. In addition, using an advanced power strip on your entertainment system reduces phantom load energy use and can save you up to $60 annually.

  Turn off your pool pump – Pool pumps are one of the largest consumers of household energy—second only to the air conditioning unit.

Reminder to Remain Diligent Regarding Heat Stress

National Grid also reminds customers that prolonged temperatures of 90°F or higher can lead to heat-related illnesses, especially for the elderly, young children and those with chronic illnesses. More information on heat stress can be found here.
