I am uncertain about this claim.

Is intensification slower for a larger system?

To me this is counterintuitive.

If anything, a larger system would draw far more air and moisture from the region.

Further, I see a gradual change between lower and higher speed winds owing to a widely spread out storm as a reason the inner core will be more intense.

I do agree on one key point here. Even though both Irma and Maria were Cat 5 people are pointing out that this hurricane is not as of yet anywhere near the size of Irma.

Here in the Pacific we do have a term for this size difference. We call some Cat 5 cyclones Super Typhoons. Hence Super denotes size.

If I remember correctly JTWC doesn't recognize the term and JTC and PAGAS do. Yet JTWC owing to being Joint with Japan adds the notation.

Twitter is going crazy with horror stories from Dominica. I hope it's not as bad as it seems.

Forecast and advisory 12 no significant changes.

Although track looks like more South and West.

In addition to bullseye hit on Puerto Rico, I think there is still a chance US mainland in play.

Even the premier of the island has his house destroyed and is asking for help. Scary

[dunno what to put here]

Maria really didn't want to be upstaged by Irma, huh?

Track in forecast 13 also moved more South West. However, looks like San Juan is in direct path.

Happened to PR in 1928 and 1899 and that was before the climate was changing.
