These are the weather blobs we pay attention to!
Multiple times each season, blobs like the ones illustrated here begin their Atlantic transit on the coast of Africa. Some, like now-active Tropical Storm Fiona, spin up early and thus, end up heading north, away from land. Others, like Invest 99 shown here in orange, track straight westward, gradually building up steam. It’s those storms that we pay attention to.
Once a storm starts to spin up, it typically then veers north, away from Grenada and the surrounding islands. Until they do though, they often head straight west, right at us. Like I said, we’ll be watching this one.
