Video Conferencing of all Weather Briefings from NEOC to Strategic Areas Housing Top Government Officials
This Season Highlighted Need for a RADAR to Significantly Improve Warning System – Especially for Late Season Systems Developing S of GCM
A WEATHER RADAR QUITE BENEFICIAL AS FOLLOWS:
System captured on Radar from as far as 300 miles away
Provide local weather service real time storm information
Allow the local weather service to observe evolution - sudden changes in the direction of motion of the storm etc.
Eliminates need to wait for Bulletins from NHC, Miami for Decision Making – Local Weather Service able to provide more frequent and highly accurate updates
Additionally this information would be fed to the Hurricane Center to improve their storm information.
Continued Public Education – Myth that Arrival Of Cold Fronts Ends TS Development – Led to less vigilance for Paloma
Need more AWOS (Robust) on all Islands to get measured parameters – Helps to avoid confusion caused by armchair experts
THANK YOU Islands (HMCI) for CIG
