Global TC [Tropical Cyclone] Activity remains at 30-year lows at least — The last 24-months of ACE [Accumulated Cyclone Energy] at 1090 represents a decrease from the previous months and a return to the levels of September 2009.
Since Hurricane Katrina (August 2005) and the publication of high-profile papers in Nature and Science, global tropical cyclone ACE has collapsed in half. Northern Hemisphere year-to-date ACE is nearing 50% below normal. The Western North Pacific is at 17% of normal (or the past 30-year average).

Ummmmmmmm ... that’s because it’s the hottest summer on record ... and ... ummmm ... we suck.
The reality is that hurricanes are not driven by just warm temperatures, but DIFFERENCES in temperature between warm and cold air. The AGW guys need to check their books on meteorology for a few minutes, and they would actually sound better.
and the weather channel is desperate for ratings...
Please read my tagline.
Obviously, more (as if any were needed) irrepudiatible (sic) evidence of .... Climate Change!!
Anthropogenic Global Warming Theory is the greatest intellectual achievement in history! It is completely unfalsifiable! All observations confirm it at the 100% confidence level!
Nearly-closed-circulation system of thunderstorms over Key West ATM ...
Nuthin posted yet though.
You mean tropical cyclones are heat exchange systems?!??!?? whodathunkit.
Completely unexpected!
We all know the drill: If it proves anthropogenic global warming, it's climate, if it doesn't, it's only weather.
This is weather.
Good news is always welcome, and this is wonderful news.
As far as the Atlantic area goes, does this mean the El Nino is returning??
El Nino and La Nina are primarily Equatorial Pacific Ocean phenomenon. Trying to correlate that to the Atlantic gets mixed results. Some experts thing you get more Atlantic Hurricanes in La Nina's, but others such a Bastardi have pointed out that we have had La Nina's with low hurricane activity in the Atlantic. We are currently in a strong La Nina combined with a Strong Cold PDO. Bastardi however is expecting an active Atlantic season based on some atmospheric effect over the NE US and North West Atlantic.
Overall however the deep oceans are very cold. That is my guess since we do not really monitor those temps much. But what else could happen when you go though 6 1/2 years of weak solar activity ? We have also been in a cold PDO phase for most of those years. PDO is a longer term Pacific Ocean Temperature trend.
I hope you are right. My understanding is that El Nino conditions produce shear winds that inhibit the development of Atlantic stoms. I live in Montana and have noticed that skiing conditions are not very good when El Nino conditions are active but are excellent during La Nino conditions. I will say that here in Montana our last winter was a dinger when the El Nino was active and our summer has been certainly cooler than usual based on my 39 years of living in Montana You can’t fool Mother Nature. :-)
A tiny bit of circulation has been evident on the Miami radar for the past day or so. The hurricane center is tracking it.
Yep. Circulation now looks to have moved into the Gulf, just west of Tampa.
It could be hugh and series.
