Dorian Mostly Misses Puerto Rico, But Florida Might Be Screwed

Healthy looking Hurricane Dorian, now well north of Puerto Rico
as seen here Thursday morning. 

Hurricane Dorian went through quite a strengthening phase on Wednesday, becoming a hurricane at least two days before most forecasters expected it to.

That it largely missed Puerto Rico is obviously good, since Dorian's peak winds had increased to 85 mph.  Not a lot of new destruction there.

But Dorian didn't interact with land, which means it stayed strong and has a great shot of getting stronger. Florida is still in its sights.

Dorian is still fighting off dry air trying to intrude. A bit of that dry air did get to the core of the storm overnight. But the National Hurricane Center warns that Dorian has a lot going for it. Relatively strong upper level winds, which can squelch hurricanes, are forecast to weaken.

Dorian is over very warm water and will remain over the toasty H2O for the rest of its journey.  That's a recipe for strengthening, and the NHC says rapid strengthening is possible over the next couple of days.

Strength forecasts for hurricanes are very tricky. Anything could happen. But the National Hurricane Center says Dorian could come ashore in Florida with winds of 125 mph - a major, destructive hurricane. Like we need another one, after Harvey, Florence, Irma and Michael over the past couple of years caused so many billions of dollars in damage in the United States.

High pressure to the north is still forecast to keep Hurricane Dorian heading to the northwest, then west toward Florida. The path is still iffy.  And nobody is sure where on the east coast of Florida Dorian might hit. Some models take it to near the Georgia/Florida border. Other models take it as far south as Miami. So the whole state is in play.

The timing now suggests that the worst of Dorian would hit Florida on Monday - Labor Day.

Predictably but wisely, Florida Gov. Ron DeSantis has declared a state of emergency, which funnels money and resourses to local governments and emergency managers to get ready for the storm, as The Weather Channel notes. 

People in Florida are spooked and getting ready for the storm. In Orlando, bottled water has already been cleared from shelves by shoppers preparing for Dorian. Lines for gasoline are really long.

However, the South Florida Sun-Sentinel says retailers have ordered extra supplies to be available in the days leading up the the hurricane, and gas supplies are still good.

Some coastal flooding is likely well in advance of Dorian, especially around Miami.  Seasonal king tides, will cause some flooding, and the approaching hurricane might help to push a little extra water ashore.

Another thing to note. If Hurricane Dorian hits south Florida, it would eventually emerge into the Gulf of Mexico. That would create a risk Dorian could gather itself up again, organize and become a threat to the Gulf Coast. We'll see.

Meanwhile, Tropical Storm Erin fizzled off the United States East Coast. As expected, it contributed to some heavy rain in eastern New England, but there fortunately wasn't a lot of flooding.

Here in Vermont, Erin contributed a bit of moisture to a slow moving cold front, so we benefitted from some decent showers.
