The tool below was designed to let you know whether you should be expecting rain or storms in your area. During heavy showers it can disrupt not only your garage but your living space entirely. By showing you the forecast of the past few hours it will allow you to prepare ahead for the rain and showers to come. There is a key on the top left of the map which you can use to see what kind and severity of rain you can be expecting on the day. Should you accidentally close it you can always click the (i) to pop it back up.
The best way to get yourself ready for a thunderstorm or torrential rain is to buy one of our garage door threshold seal kits, as it is designed to stop any and all rain from entering your garage. Some of the larger models were designed to act as flood barriers, and if it looks like flooding is going to happen you should absolutely consider getting one.
