It can happen to you when you least expect it - a storm billows up and causes damage to your property.
Taking care of your house as soon as possible after a damaging storm is important! Let Rescue Roofing Specialists repair any issues and work with your Insurance Company, so that you can rest easy and focus on other things.
We've provided some interesting information on hail*, so that you can be prepared on what to expect should a strong storm come through your area.
What is hail?
Hail is precipitation that is formed when updrafts in thunderstorms carry raindrops upward into extremely cold areas of the atmosphere and freezes into ice. Hailstones grow by colliding with supercooled water drops. Thunderstorms that have a strong updraft keep lifting the hailstones up to the top of the cloud so they continue to grow. The hail falls when the thunderstorm’s updraft can no longer support the weight of the ice. The stronger the updraft, the larger the hailstone can grow.
Can we predict hail?
Hail can be predicted using radar. On Doppler radar, hail generally sends a return signal that looks like extremely heavy rainfall. We are also studying the use of polarimetric radar (radar that sends horizontal and vertical pulses) because it can detect actual ice, and determine the location of severe hail.
How does hail fall?
My neighbors on both sides had hail damage to their roofs, and I did not. How is this possible? NSSL works to predict hail, we do not study hail damage from an engineering perspective. However, there are a number of reasons why your roof did not show damage. It is possible that your roof had better shingles, or newer shingles. The direction of your main roofline, the distance between the houses, whether or not the wind was driving the hail – all these can make a difference in the amount of damage you can receive.
Is there a way to find out the peak hail season in my area?
By using NSSL’s Severe Thunderstorm Climatology graphs you can see the annual cycle of the probability of any type of severe weather occurring within 25 miles at any point you select.
How fast does hail fall?
How hail falls is dependent on what is going on inside the thunderstorm. Hail falls when it becomes heavy enough to overcome the strength of the updraft and is pulled by gravity towards the earth. Hailstones bump into other raindrops and other hailstones inside the thunderstorm. This bumping slows down their fall. Drag and friction are also factors. We really only have estimates about the speed hail falls.
Can "normal" thunderstorms able to product large hail?
Yes, many non-supercell storms produce golf ball size hail.*This information is provided by the National Severe Storms Laboratory and NOAA.
