Definite props go to JB for calling this one. Just a few days ago, there were those calling people people I disagree with for thinking this could be more then a minimal tropical storm. The Gulf stream(yes to answer the question above) combined with improved upper level conditions made for this to become one heck of a storm to look at!

Drec...do you base tropical conditions only based on winds? I hope not! There is so much more to the tropics...such as storm surge...rain...erosion. All which combines to cause 'damage' I am sorry but going to be kinda forceful on wording this. The people on Hatteras will not be looking at Alex as only 'Tropical storm' conditions...Last night they were only expecting a tropical storm that they were probably only gonna see the edge of! Now they are rideing the eyewall of a pretty good Cat 2 storm..yes the northwest side..but what the NHC still is classifying A CAT 2 HURRICANE... Personally your downgrading harping of this depresses me.

So ... just why Alex caught even us offguard ...
Well, simple ... not ONE of us expected this to become a hurricane in its incipient stage, let alone Cat 2. Second, we all basically had to play catchup ... which lends to the old addage, that intensity forecasts are ALWAYS the hardest to predict ...
Alex is a small compact storm very susceptible to subtle changes either for or against it ... yesterday, when the s/w ridge built over top of the system, it responded very quickly with a strong burst of convection as the NE Shear relaxed ... (however, there was ENHANCED divergence or diffluent flow which aided in the development of the convection) ... As the s/w ridge became more established, convection was able to build and wrap around the center in a much more organized fashion, and we also saw, the vertical profiles begin to match up instead of the chaotic mess just 24 hours previous, with low level swirls exiting out of the NNE side of the storm, and the MLC meandering ...
Yesterday afternoon, and evening, during the diurnal mininum, we saw convection fade out somewhat but still enough to allow Alex to hold its own. As the afternoon wore on, another very strong burst of convection occurred, and again, an enhancement was caused by a small jet streak in the RRQ of the trough which placed diffluent flow right over Alex, and allowed for another round of intensification. Southwesterly winds increased aloft, but also, the cyclone also responded by picking up speed yielding lesser amounts of shear. The small size of Alex allowed for pressures to come down fairly quickly (but not in the classification of rapid), and also the high Heat Potential in the Gulf Stream makes Alex - "the storm that seized the window of opportunity to the fullest" ...

Well, they have been under a tropical storm warning since Sunday at 11 am, and it was upgraded to a hurricane warning last night (Monday) at 5 pm. And 65 mph sustained with gusts barely into hurricane force is in fact typical TS force winds. No doubt Alex is a hurricane with sustained hurricane force winds on the other side of the eye, though.

Thanks HG... 3 inches an hour is what we don't need. We're already saturated from recent rains.
I am working in Duck today... our parking lot is flooded due to heavy rains. The winds are picking up and our power is blinking.
At the same time, our island is crammed with tourists who are spending the day "rubbernecking"... so the roads are not only flooding... they're packed.

Conditions getting worse up the beach.
Buxton: from a gentleman standing on the beach: "worse it's been so far"
winds 60-70mph rough estimate
Winds ENE
no significant ocean surge
Avon: worse so far
NE winds near hurricane force; stoplights blowing horizontally; no flooding
Trying to get in touch with Hatteras, but having some trouble.
