The Atlantic storm map is wiped clean. Isn't that a bit odd?

Hours after the National Hurricane Center issued its last advisory on what was a post-tropical Karl in Mexico and marked a tropical wave several hundred miles southwest of the Cabo Verde Islands on Saturday morning, the 1 p.m. advisory map is as clean as one could hope for during the hurricane season.

But is that unusual?

Not really, explains Brad Reinhart, a hurricane specialist with the National Hurricane Center.

“As you know, the peak of hurricane season is typically mid-September and now that we’re here in mid-October, historically, this is the time of year when we start to see a pretty sharp decline in the amount of overall tropical storm and hurricane activity. So it’s certainly not unprecedented that there are stretches this time of year where as the tropics wind down there might not be development for several days,” Reinhart said.
