  1. Hurricane Maria Discussion Number  12
    NWS National Hurricane Center Miami FL       AL152017
    1100 PM AST Mon Sep 18 2017
    
    The Air Force Hurricane Hunters were able to fly a single pass
    from northwest to southeast through the eye of Maria just prior to
    0000 UTC.  The aircraft found a peak SFMR wind of 139 kt in the
    northwest eyewall, i.e. category 5 intensity.  Raw objective
    T-numbers from UW/CIMSS reached as high as T7.3 just before the
    center moved over land.  Based on these data, the initial wind speed
    was increased to 140 kt on the earlier special advisory, and that
    intensity is maintained for this advisory, although some slight
    weakening may have occurred as the small core of the hurricane
    passed over Dominica.  Since the center has moved over land, the
    aircraft has not been able to make a second pass through the eye.
    The aircraft will be in the storm a few more hours and should be
    able to provide additional center fixes once the eye moves west of
    Dominica.
    
    Maria is forecast to remain within an environment of low wind shear
    and over warm water during the next couple of days.  Given these
    favorable atmospheric and oceanic conditions, Maria is expected to
    remain a Category 4 or 5 hurricane when it approaches the Virgin
    Islands and Puerto Rico, however some fluctuations in intensity are
    possible due during the next 24 to 36 h due to eyewall cycles.  Land
    interaction and a slight increase in shear are likely to cause some
    gradual weakening after Maria moves over the southwestern Atlantic
    in 3 to 4 days.
    
    Maria is moving west-northwestward or 300/8 kt.  A weak ridge
    located over the western Atlantic is expected to steer the
    hurricane west-northwestward through 48 hours, and on this track the
    center of Maria is forecast to pass near or over the Virgin Islands
    and Puerto Rico on Wednesday.  After that time, the western portion
    of the ridge is forecast to weaken, which should allow Maria to turn
    northwestward, then north-northwestward by day 5.  The track
    guidance is in good agreement and little change was required to the
    NHC track forecast through 72 hours.  At days 4 and 5, the global
    model envelope has shifted slightly eastward and the NHC forecast
    was adjusted accordingly to be in better agreement with the HFIP
    correct consensus and ECMWF model.
    
    
    KEY MESSAGES:
    
    1. Maria will affect portions of the Leeward Islands and the British
    and U.S. Virgin Islands as an extremely dangerous major hurricane
    during the next couple of days, and hurricane warnings are in effect
    for many of these islands.
    
    2. Maria is likely to affect Puerto Rico as an extremely dangerous
    major hurricane, and a hurricane warning is in effect for that
    island.  Preparations to protect life and property should be rushed
    to completion.
    
    3. The potential for a life-threatening storm surge, accompanied by
    large and destructive waves, has increased for the Leeward Islands,
    the Virgin Islands, and Puerto Rico.
    
    4. Life-threatening flash floods and mudslides from heavy rainfall
    are expected across the Leeward Islands, including Puerto Rico and
    the U.S. and British Virgin Islands.

  8. Anything before 2003 I don't remember much of, so I am basing my ratings after that storm.  In '96, I was stuck in FL for my grandparents' 50th wedding aniversary, so I missed that storm completely... it was hell to get a flight back into DCA from JAX...

     

    Jan 2000 -- All I really remember was listening to my weather radio and hoping beyond hope Bob Ryan was wrong (that we would get grazed by the SLP at best, one inch at most) and hearing my weather radio go off ~10PM and WSWarnings being issued for 4-8 inches for us... then 6-12 later that night and so on.  I remember running downstairs to my dad and telling him -- he didn't believe me until he saw the warnings himself :lol:

     

    2009-10 season as a whole was the best... I remember being on the computer alot where I work and not getting much done during the December storm and the February storms since I was tracking the storms so much... luckily most of the admin knows I am a "weather nerd" so they let me do some model watching as long as I did some work :lol:

     

    If I had to pick one, probably the Feb 5-6 storm first

  9. I hardly even remember PD2.  I'd suspect it's because I was working (bartender) and drunk pretty much the whole time because barely any other restaurants were open for a few days afterwards.

     

    I got stuck in Wilkes-Barre, PA during '96.  We got about 20" up there, while my hometown in Jersey got 33".

     

    December 18-19 was an awesome storm, but its 22" was almost dwarfed by the 27" from Feb 5-6.  I only got 8-9" from Feb 10, but the morning blizzard band was pretty sick.

     

    No doubt, though, that Dec 18-19 was in my top 5 all time. Easy.

    96 we were stuck in FL (JAX) for a family vacation and it was tough getting back in... we got one of the last flights back from RDU to DCA.  09-10 was awesome for both storms, both the Dec and Feb ones.

  10. I remember being at work and getting absolutely nothing done... staff members were coming up to me and asking me about the weather all day... I was supposed to help write up a lesson plan for the next week (right before Christmas break) but I never did it cause I knew that we weren't going to be in school.

    Remembering how the NAM was giving the LWX region 2.5" liquid and we all thought that was outrageously high... I'll think of more
