There's a radar loop showing Dean's approach to the Yucatan Peninsula available at: http://einstein.atmos.colostate.edu/~mcnoldy/tropics/dean07/Dean_20Aug07.gif
Dean will also pass about 75 miles south of a buoy in a few hours (around 23Z)... the buoy reports wave height, pressure, wind speed/gusts, etc. Although it won't be a direct overpass, we'll get some idea of the near-core environmental surface conditions.
Wave height:

Surface Pressure and winds:
http://www.ndbc.noaa.gov/show_plot.php?station=42056&meas=wdpr&uom=M
The intensity as of 18Z is 130kts and 924mb.
Storm surge along the northern Yucatan Peninsula is expected to reach 12-18 feet above normal. Dean is forecast to become a CAT5 hurricane later today/tonight.
