Hurricane Rina in Western Caribbean
|
Line D. Estimated (by SFMR or visually) Maximum Surface Wind: 65kts (~ 74.8mph)
Line H. Minimum Sea Level Pressure: 991mb (29.26 inHg)
991mb gives us a Maximum Possible Wind Speed of : 84 mph
1000mb-991mb= 9+75mph=84mph
So Rina is currently below the pressure/ wind speed curve.
NHC has upgraded Rina to a Category One Hurricane based on RECON data.
