Tropical Weather Outlook (TWO)
      #79768 - Tue Apr 08 2008 08:31 PM

Just fyi - from the National Hurricane Center:

The 2008 version of the GTWO will be issued four times per day.

The 2008 version of the GTWO will include a three-tiered, color-coded, categorical genesis forecast:

The issuance times for the TWO and GTWO will be changed to 0000, 0600, 1200, and 1800 UTC. In previous years, the Atlantic TWO was issued at 5:30 AM, 11:30 AM, 5:30 PM, and 10:30 PM, ET while the Pacific TWO's were issued at 4 AM, 10 AM, 4 PM, and 10 PM, PT.

Cheers,
ED

Hurricane Experts Likely to Raise 2008 Storm Predictions Today

By Demian McLean

April 9 (Bloomberg) -- Hurricane forecasters probably will boost the number of expected 2008 Atlantic storms when they update their prediction for the season today, meteorologists say.

William Gray and Philip Klotzbach of Colorado State University, whose predictions are closely watched by insurers, energy markets and local governments, are scheduled to release their forecast by 11:30 a.m. New York time. Their preliminary report in December predicted 13 named storms this year, including seven hurricanes, three of them major.

``We think the forecast is going to be relatively aggressive,'' Michael Schlacter, chief

I`ve got a question. Is it possible for a tropical cyclone to reach Cat 6 strength or are there natural contraints that would prohibit pressure dropping low enough that it would create wind speeds over the Cat 5 treshold. I`ve also heard some talk about a "Hyper Cane " . Is this science fiction or is there some truth that it is possible that a storm of this magnitude could one day form in the Atantic or Pacific Basins. I know we`ve had some low pressure records set over the last several years in both areas.......Weatherchef

There isn't anything beyond category 5, at least not in operational use; categories 6 and 7 and beyond are merely the realm of Hollywood.

Hypercanes are possible but not plausible. It's much more likely that, should the SSTs needed for such intensities be reached, that disorganized convection spontaneously forms across that region. This would serve as a throttle on TC development and, to some degree, the SSTs themselves.
