 Note red line is latest NHC forecast track. The others are previous from the morning.  You can see the NHC has had to adjust their track further to the south or left of previous track.  This is due to the high pressure ridge to Irma's north curving southwestward and this forces the storm to track West of due South.  That will have to watched closely, because this could change forecast for the Northern Leeward Islands and put then in harms way.  This also changes the tracks further west.  Keep monitoring closely and Leeward Island be ready for a hurricane if it does not shift northward...RTW
