As feared, Matthew is strengthening explosively. Special statement was just issued showing surface winds up from 80 mph at 11 am to 100 mph by 1:20 am with the last pass of the hurricane hunter aircraft. Could be a major hurricane by the time it comes close to or hits one of Jamaica/Cuba/Haiti and it if doesn't get sheared apart too much, it could still be cat 2/cat 3 entering the Bahamas. Still way too far out to know where it goes from there - basically anywhere from MS to FL to NC to a complete miss.

As expected, the special 2 am update is in with a major increase in forecast intensity, given that the starting point, now, is already up to 100 mph - forecast is now for a Cat 3 storm with 120 mph winds in the next 2-3 days and it could get even stronger than that as conditions (low shear, very warm sea surface temps, minimal dry air) are conducive for strengthening.
So, it looks like another round of watchful waiting with a hurricane that could impact our area 7-8 days from now. Matthew has gone from a ragged tropical wave early Wednesday morning to a 60 mph tropical storm at 11 am Wednesday to an explosively strengthening Cat 2 hurricane as of 2 am Friday, with winds up to 100 mph (from 80 mph just 3 hours ago!) and pressure down to 979 millibars, which is a major drop of 4 mbar in 3 hours (and 14 mbar in 9 hours).
Areas from Jamaica to Eastern Cuba to Haiti are really now at risk from what will likely be a major hurricane with winds in excess of 110 mph in a couple of days when it nears those areas (by Monday). There will also likely be torrential rains and major storm surges for anywhere the storm hits. And then by Tuesday, the storm, which may not weaken much, after it approaches/crosses Cuba from the south (traversing the minimal length of land), will take aim at the Bahamas.
Where it goes after the Bahamas is very uncertain, as models are showing everything from a jog to the west, into the Gulf of Mexico, with landfall anywhere from MS to AL to FL, to a direct hit on Florida, to a run up the coast to NC to a near miss and out to sea off the east coast. It's unlikely, but possible, for Matthew to come up the east coast (perhaps after going inland across NC) and then impact our area by late next week.
PLEASE DO NOT BELIEVE ANYONE WHO SAYS THEY KNOW WE'RE GOING TO BE HIT BY THIS STORM. Of course, it's possible, but nobody on the planet can predict a hurricane's path and intensity that far out. Stay tuned.
The Weather Underground and the NHC are the best sources of information for tropical systems.
