The National Weather Service issued a severe thunderstorm warning at 4:04 p.m. on Wednesday that is in effect until 5:00 p.m. for Fulton and Montgomery counties.

Expect half-dollar (1.25-inch) sized hailstones and wind gusts up to 60 mph.

“At 4:04 p.m., a severe thunderstorm was identified near the Caroga Lake Public Campground or near Gloversville, moving south at 25 mph,” the weather service says. “Hail damage to vehicles is expected. Expect wind damage to roofs, siding and trees.”

Places affected by the warning include Gloversville, Johnstown, Canajoharie, Fonda, Fort Plain, Ephratah, Caroga Lake, Tribes Hill, Caroga Lake Public Campground, Glen, Berkshire, Charleston, Fultonville, Palatine Bridge, Nelliston, Bleecker, Auriesville, Meco, Cook Corners and Sprakers.

The weather service states: “For your protection, move to an indoor location on the lowest level of a building. This storm will produce heavy hail, damaging winds, and sustained cloud-to-ground lightning strikes. Get indoors immediately. Lightning is one of nature’s greatest killers. Remember, if you hear thunder, you are close enough to be struck by lightning. This storm will produce torrential rains that may cause flash flooding. Do not drive your vehicle through flooded roads.”

When lightning threatens: Safety tips from experts during thunderstorms

Lightning strikes occur about 25 million times each year in the United States, with most of these electrifying events occurring during the summer months. Unfortunately, about 20 people are killed by lightning strikes each year, according to the Weather Service. The danger from lightning strikes increases as thunderstorms approach, reaching its peak when the storm is directly overhead and gradually diminishing as it moves away.

To ensure your safety during a thunderstorm, follow these recommendations:

Lightning protection plan:

• When you are outdoors, it is important to have a clear plan for seeking shelter in the event of a lightning strike.
• Stay alert by watching the skies for ominous signs and listening for the telltale sound of thunder. If thunder is audible, it is a clear sign of lightning nearby.
• Immediately seek shelter in a safe place, preferably indoors.

Indoor safety measures:

• If you have found shelter in a building, refrain from using corded telephones, electrical appliances or plumbing and do not approach windows and doors.
• Lightning can follow conductive paths and these precautions reduce the risk of electrical surges.

Wait for the all-clear:

• Wait at least 30 minutes after the last lightning strike or clap of thunder before resuming outdoor activities.
• Remember that lightning can still strike even after a storm appears to have passed, so be careful.

If no shelter is available in the house:

If you are outdoors during a thunderstorm and do not have access to shelter, take the following steps to maximize your safety:

• Avoid open fields, hilltops or ridges where the risk of lightning strikes is greater.
• Stay away from tall, isolated trees and other prominent objects. In forested areas, stay close to lower stands of trees.
• If you are traveling in a group, make sure that everyone keeps a sufficient distance from each other to prevent the lightning current from being transmitted between people.
• Camping outdoors during a thunderstorm is strongly discouraged. If you have no other options, set up camp in a valley, ravine, or other low-lying area. It is important to note that a tent does not provide protection from lightning strikes.
• Do not approach bodies of water, wet objects, or metal objects. Although water and metal do not attract lightning, they are good conductors of electricity and can pose significant risks.

In summary, preparation and vigilance are your best allies when you are at risk of being struck by lightning. By following these guidelines, you can significantly reduce the chances of being struck by lightning and put your safety first.

Mastering wet roads: safety tips for heavy rain

When heavy rain sets in, the risk of flooding and dangerous driving conditions increases. Whether it’s persistent rain or rapid runoff, it’s important to be prepared. Here are some valuable safety tips from the weather service to help you stay safe during heavy rain:

Be careful with fast water flow:

During heavy rain, do not park or walk near culverts or drainage ditches as fast-flowing water can pose a great danger.

Keep the safety distance:

Use the two-second rule to maintain a safe distance from the car in front of you, and add an additional two seconds in heavy rain.

Slow down and be careful:

On wet roads, it is important to reduce speed. Slowly ease off the accelerator and avoid sudden braking to prevent skidding.

Choose your lane carefully:

Stay in the middle lanes to minimize the risk of aquaplaning. More water can collect in the outer lanes.

Visibility is important:

Improve your visibility in heavy rain by turning on your headlights. Pay particular attention to vehicles in your blind spot, as rain-smeared windows can obscure them.

Be careful of slippery roads:

During the first half hour of rain, the roads are most slippery due to a mixture of rain, dirt and oil. Be especially careful during this time.

Keep a safe distance from large vehicles:

Do not drive too close behind large trucks or buses. The spray created by their large tires will limit your visibility. Also be careful when overtaking; if you must overtake, do so quickly and safely.

Pay attention to your windshield wipers:

Overloaded wiper blades can reduce visibility. If rain is severely affecting your visibility, pull over to the side of the road and wait for conditions to improve. Seek shelter in rest areas or places sheltered from the wind.

If the side of the road is your only option, pull over as far as possible, preferably to the end of a guardrail, and wait for the storm to pass. Keep your headlights on and turn on your hazard lights to alert other drivers to your position.

In heavy rain, these precautions can go a long way to keeping you safe on the road. Remember to check weather conditions and follow the instructions of local authorities to ensure a safe journey.
