What is a Squall line?

9/21/2021 (Permalink)

A squall line is a narrow line of fast-moving storms. They have the ability to span hundreds of miles from top to bottom, yet are typically less than twenty miles across.

These storms can hold together for days at a time and cover multiple regions of the United States. Strong cold outflow winds help push these storms forward, which means tornadoes are usually not the main threat, but that doesn’t mean these storms aren’t dangerous. Relentless rain, powerful straight-line winds up to 90-mph, and intense lightning all typically accompany squall line storms.

Because squall lines tend to be accompanied by lagging smaller cell storms, flooding can be a common hazard. In the case of flooding for residential or commercial properties, our team of trained professionals is ready and eager to assist you with any size job. If a squall line does produce a tornado, it will usually be detected at the front of the line of storms. This is different from supercell storms, which tend to produce tornadoes on the rear side of the storm. Storms and other natural disasters can come at any time so you should always have a plan in place. Our goal is to help you get back on track as quickly as possible so we can all get back to enjoying our homes. Whether it's a fire or a storm, your safety is our first priority.
