"Dry thunderstorms" are thunderstorms that produce little or no precipitation at the surface. In combination with dry fuels (i.e. vegetation), dry thunderstorms can ignite fires with lightning, but won’t provide much rain to put the fires out. Therefore, dry thunderstorms are a factor in fire weather forecasts. weather.gov/abq/clifeature2010drythunderstorms

Hail forms when updrafts (or rising air) in thunderstorms carry raindrops upward into extremely cold areas of the atmosphere, allowing the raindrops to freeze. The stronger the updraft, the bigger the hailstone can become before falling out of the storm (typically when the hailstone becomes too heavy for the updraft). The largest hailstone in diameter was 8 inches, which fell in Vivian, SD on July 23, 2010. weather.gov/jetstream/hail

Hail is precipitation that forms when thunderstorm updrafts (or rising air) carry raindrops upward into extremely cold areas of the atmosphere, where the raindrops freeze into hailstones. Big updrafts result in big hail. weather.gov/jetstream/hail #WeatherReady

Thunderstorms can be a mariner's worst nightmare. They can develop quickly and can produce strong wind, pounding rain, deadly lightning, and damaging hail with very few places for shelter. Even marginal thunderstorm winds can capsize certain boats and other floating vessels. If you are out on the open water and see clouds quickly growing in the distance, it may be thunderstorms that are developing. Don’t wait until you can hear thunder or see lightning. It is best to head to port or safe shelter at the first sign of a developing storm. weather.gov/safety/safeboating-during

Thunderstorms can produce heavy rain, which may lead to flooding. Watch out for water of an unknown depth - it only takes 6 inches of flowing water to knock over a person, and 12 inches to carry away a car. If you can’t see the road, Turn Around Don’t Drown! weather.gov/safety/thunderstorm
