Now that Nana has dissipated and Omar is just about to, our attention will shift to a series of tropical waves emerging off Africa. The first two waves, dubbed 91L and 92L by the NHC, are slowly developing over the Eastern Atlantic this afternoon.

Satellite imagery this afternoon shows sporadic convection associated with both systems. The next wave (not yet given an “invest” classification) is the most convectively active this afternoon, but that’s mostly because it’s getting a boost from heating over the African continent. None of these systems are likely to develop in the imminent future this weekend, but 92L is likely to develop by the time we get to early/mid-next week.

The National Hurricane Center has set the odds of development within 5 days at 30% for 91L, 80% for 92L, and 60% for that next wave. By the middle of next week, we’ll probably have one or two (possibly three) named storms spinning in this part of the Atlantic.

What comes next? Steering currents are relatively weak so any storm that does develop here won’t be moving fast. Right now, it looks like odds are in favor of any system developing in this region over the next week to recurve before it makes it far enough west to impact land. So while I can’t rule out impacts just yet, I’m not too concerned about these systems at the moment.
