We get dust every year from Africa. It blows across the ocean with the trade winds around this time of year and we normally don't notice it much. But they said this one's exceptionally heavy and warned people with respiratory issues to be a little more careful when outside.
Accuweather has an article about it along with a radar loop showing both huge clouds. The second one wasn't mentioned during our weather forecast but I guess they'll wait until it's closer. The first one is supposed to start hitting us tomorrow night.
You stay safe...will it suck up any rain you might get, or be a non-issue for storms?
