The top wind is now near 140 mph. Hurricane force wind extends to 35-40 miles from the eye. Ian will move inland near Port Charlotte later today without much change in intensity.

A Resurgent Madden Julian Oscillation Ahead!

Madden Julian oscillation shifts to phase_4/phase_5 and strengthens over the next 2 weeks according to ECMWF. The convection pattern in the tropics of the West Pacific suggests this pattern has already developed. An increase in West Pacific tropical cyclone activity and above normal rainfall stretching from Southeast Asia to Australia is likely. Conversely, the subsidence phase of MJO shifts across South America.

After Ian, West-central/Central North Atlantic Tropics Stay Busy According to ECM

ECM "weeklies" have been helpful identifying periods of anomalous rainfall in the deep tropics/subtropics implying presence of tropical cyclone activity. The model is persistent at producing that risk for the west-central/central North Atlantic tropics/subtropics through October.
