Have to say good Job to the NHC for being on top of things... u can tell there watching the AF recon data and the buoy data... They have issued a few special adv. this morning before the main adv. pkg comes out... they adjusted the short-term path in a 115am adv...
THIS SPECIAL ADVISORY IS BEING ISSUED TO ADJUST THE SHORT-TERM INTENSITY AND TRACK FORECAST OF IDA. BASED ON THE OBSERVED INTENSIFICATION OF THE SYSTEM IN THE LAST FEW HOURS...THE INTENSITY FORECAST IS RAISED TO 85 KT AT 12 AND 24 HOURS...WITH THE POSSIBILITY THAT IDA COULD GET A LITTLE STRONGER THAN THAT SOMETIME TODAY. BEYOND 36 HOURS...THE INTENSITY FORECAST IS UNCHANGED FROM THE PREVIOUS ADVISORY.
