According to the Saffir-Simpson Wind Scale at 0200 a.m. AST Wed Sep 12 Hurricane Florence belongs to Category 4.

Maximum sustained winds: 60 m/s
Minimum central pressure of 949 mb, located at 28.5N and 69.5W with a west-northwest movement at about 8 m/s.

The numerical simulation is prepared by real initial GFS fields with 0.25 degree resolution and the lateral boundary conditions taken at each 3 hours. The forecast length is 3 days ahead.

Animated files with hourly loops show:

• MSL pressure (hPa) and 10m wind (m/s)
• Absolute vorticity (10-3/s)
• Total accumulated rainfall (kg/m2)
• 0-6000 m above ground Mean storm motion
• 700 hPa level Relative humidity (%)
