Emily is at this time a Category Three Hurricane, and some intensification is expected over the next 24 hours, taking Emily to Category Four.
The high pressure area in the vicinity of the Cayman Islands continues to raise expectations that Emily will continue on a more southerly course. However, with Emily's anticipated intensification into a dangerous Category 4 Hurricane, this weather system is a major threat to the Cayman Islands and there is always potential for change.
NHC advice to local population: The NHC this evening urged all interests to closely monitor news reports. Residents and businesses have been urged to begin planning for preparations, which should be in process tomorrow (Friday morning, 15th.).
The NHC continues to urge residents not to leave preparations until Saturday, but to begin on Friday as soon as possible.
In a comment following the 4:30 pm meeting, NHC Chairman Donnie Ebanks stressed: 'It is important that everyone gives this system the attention and respect that it clearly warrants. All businesses should ensure that preparations are given priority tomorrow morning so that whenever businesses close, all preparations are complete. At the same time, employers should ensure that employees are given opportunity to attend to personal arrangements if necessary. Coming so close on the heels of the preparations for Hurricane Dennis, it should be quite feasible for most businesses to meet both of these important obligations and still maintain normal operating hours tomorrow (Friday),' said Chairman Donnie Ebanks.
NHC actions: Committee chairmen were expected to commence preparations in their various areas on Friday morning, including shuttering government buildings and preparing shelters, etc.
