Hurricane Dean was the third-most intense Atlantic hurricane to make landfall since record keeping began in the 1850s, based on its central atmospheric pressure
Dean was a top-scale Category 5 storm at landfall Tuesday on Mexico's Yucatan Peninsula. Its maximum sustained winds were near 165 mph and gusts reached 200 mph. Just before landfall, a Global Positioning System device dropped from a hurricane hunter aircraft found it had a central pressure of 906 millibars.
The only other storms that hit land with a lower pressure were the 1935 Labour Day hurricane that hit the Florida Keys and Hurricane Gilbert, which hit Cancun, Mexico, in 1988.

ESA satellites are tracking the path of Hurricane Dean as it rips across the Caribbean Sea carrying winds as high as 260 km per hour. The hurricane, which has already claimed eight lives, is forecast to slam into Mexicos Yucatan Peninsula on Tuesday morning.
Dean was upgraded early Tuesday to a Category 5 the highest on the Saffir-Simpson scale before pummelling the peninsula. Knowing the strength and path of hurricanes is critical for issuing timely warnings; satellites are the best means of providing data on the forces that power the storm, such as cloud structure, wind and wave fields, sea surface temperature and sea surface height.
Instruments aboard ESAs Envisat and ERS-2 satellites allow them to peer through hurricanes. Envisat carries both optical and radar instruments, enabling researchers to observe high-atmosphere cloud structure and pressure in the visible and infrared spectrum.

Hurricane Dean ploughed into the Caribbean coast of Mexico early Tuesday as a roaring Category 5 hurricane.
Officials at the U.S. National Hurricane Centre said the eye of the storm reached the coast at 1:30 a.m. PDT. They were still working to pinpoint the location.
