REMARKS:
The combination of NW shear (>20 knots) and cooler sea surface temperatures have resulted
in the death of Ophelia overnight. Although the 10UTC Quickscat showed some area of gales in southern quadrants the 14UTC ASCAT pass confirmed Dvorak estimates of below cyclone
intensity.
Dvorak: FT=1.5 CI=2.5. Convection may maintain 25-30 knots in southern quadrants today.
Notes:
This product is issued every six hours; the Cyclone Advices (Watches and Warnings) are
usually issued more frequently and contain more useful information for coastal communities.
Time Conversion from UTC to local:
WST add 8 hrs (Add another hour for daylight saving)
CST add 9 hrs 30 min
EST add 10 hrs (Add another hour for daylight saving)
