Just for the record, whenever the windspeed increases the weatherguy
increases the rainfall estimates. obviously they have nobody under the
hurricane with rain gauges, so i think they are using a tried-but-true
formula.
Here's from the last report:

You might also notice the speed of increase: Advisory 12A 2pm 75mph,
Advisory 15A 2AM 175mph.
4-6 inches rain went to 10-15 inches of rain. Size (diameter) never
changed. The windspeed alone is elevating water by the mega-tonnages.
Who sez SIZE doesn't matter? Guys with Cat 1 endowment, that's who.
You know what Hoggle is packing in his jeans when he sez size doesn't
matter...
