W3FT210

The W3FT210 routine converts a northern hemisphere 1.0 degree
            lat.,lon. 361 by 91 grid to a regional - Puerto Rico
            (Mercator) 25*25 AWIPS 210 grid.

USAGE:  CALL W3FT210(ALOLA,AMERC,INTERP)

   Input arguments:
      ALOLA  - 361*91 GRID 1.0 DEG. LAT,LON GRID N. HEMI.
