A huge dust storm off the coast of Africa could make it all the way to the coast of the southeastern United States. ?This Saharan Dust storm is visible on satellite. ?At first glance, this might look like a big rain storm or tropical system moving off the coast of Africa. ?This is actually a huge dust storm carrying sand and mineral dust particles in the air out into the Atlantic Ocean.
This is something we want to watch for a couple of reasons. ?Often, these storm help to suppress tropical development as it travels across the ocean. ?Many times, particles act as a "condensation nucleii" to help form a raindrop. ?But when there are a lot of particles, that moisture spreads out to attach to many particles rather than just a few. ?Since the moisture is spread out, it suppresses rain from developing. ?This could hinder tropical systems from developing as the dust storms travels to the east.
Another reason we need to watch is because this dust could make it to the SE coast of the United States. ?Many time, Saharan dust will make it to the coast of Florida. ?If this happens over the next week or so, sunrises in Florida will appear reddish as the rays of light travel through the dust. ?It could also hinder rain development in Florida depending on how thick the dust is. ?It is too early to tell if this dust would have any affect on Georgia. ?Right now, the forecast models take this dust layer well to the south.
Something interesing to watch in the immediate future! ?NASA has a special project studying Saharan Dust and the effect on tropical systems. ?Looks like they have a good one to study this year!
