Up near 90 in the waters around southwest Florida.

Fuel for rapid intensification if a hurricane tracks over that area with no wind sheer and optimal conditions.

This is an anomaly map showing temps compared to average. Some very unusual temperature configurations.

1. Note the VERY warm Atlantic

2. Note the warm water El Nino in the Eastern tropical Pacific.

3. Note the unusually cool water off the  West Coast-really strange.

4. Note the intense warm blob in the Northeast Pacific.

The warm blob north of the cold in the Pacific is causing a strongly negative -PDO!

This is very odd. Usually, strong El Nino's like this upcoming one feature a positive +PDO and warmer water where there is cold water right now:

Note the maps below with a typical -PDO on the right........during LA NINA's!

The El Nino anolog on the left features cold anomalies to the north and warm water along the West Coast and a +PDO. 

It's a total disconnect with how the pattern looks historically.

I haven't searched around for any explanations for this oddity, maybe Larry has seen some.
