HURRICANE DEAN SUPPLEMENTAL UPDATE 17:30 Hrs USA CDT, August 20, 2007
After devastating parts of Jamaica and doing significant damage on Grand Cayman Island, Hurricane Dean will make landfall on the eastern Yucatan Penninsula Tuesday morning, August 21. It will then loose some of it's strength by passing over the mountains in the area and re-emerge into the southern Gulf of Mexico later Tuesday. At this time, the storm track will cross the southern Gulf of Mexico and place the hurricane on land in east central Mexico early Wednesday morning August 22. The weather system timing that was so critical to the storm making any northerly turns has not materialized. However, since this storm is so wide, persons in southeastern Texas coastal areas are preparing for gusty winds and significant rainfall starting late Tuesday into Thursday and Friday. This storm may possibly strengthen to Category 5 levels later tonight. Our next update will be around 05:30 AM Tuesday August 21. http://www.nhc.noaa.gov/ ================================================== ======= "THIS IS NOT AN OFFICIAL ADVISORY.

Major Hurricane Dean has attained Category Five status with sustained winds at 160mph, and is expected to strengthen further before making landfall on the Yucatan Peninsula.
Conditions have rapidly deteriorated, and this system could become one of the strongest landfalling storms on record at the point of landfall. The Buoy at http://www.ndbc.noaa.gov/station_page.php?station=42056 is reporting 35 foot waves, much higher than a typical single tsunami event. To put this in perspective, lets review a deadly F3 tornado's impact: -=-=-=-=-=-=-=-=-=-=-=-=- F3 Severe tornado 158-206 mph Roof and some walls torn off well constructed houses; trains overturned; most trees in forests uprooted. -=-=-=-=-=-=-=-=-=-=-=- Now, most tornados last around 30 seconds. Imagine this impact for over 3 hours, up to 12+ hours. While you have that firmly in mind, add a massive, unrelenting push of water, ultimately raising the water levels by up to 20+ feet. Once you have that firmly in mind, add spin off tornados, while all the rest is going on. One more to add, think about all of that then drop 20 inches of rain per hour. It is a truly devastating scenario. Elsewhere in the tropics, Invest 92L continues to look disorganized, but conditions are favorable for some slow development. This system has more potential to pose a threat to the United States than Major Hurricane Dean, however, the intensity of this system should be much less. |

HURRICANE DEAN UPDATE 05:30 Hrs USA CDT August 21, 2007
Category 5 - The highest level of Hurricane on the Saffir-Simpson devastation scale... That is what has made landfall in the Yucatan Penninsula of Mexico. Current winds are at 165 miles per hour with gusting to just under 200 miles per hour. This catastrophic, deadly storm will move across the Penninsula today and re-emerge into the southern Gulf of Mexico where it will continue on it's westerly track and make a second Mexico landfall near coordinates 20 North by 96.5 West on Mexico's eastern Gulf Coast. Persons in coastal areas of southeastern Texas can expect very high winds, significant rainfall, localized flooding, some storm surge and beach errosion from the right quadrant of this hurricane. Our next scheduled update will be Wednesday morning at around 05:30 AM CDT. Until then, use the link below for official updates and information. http://www.nhc.noaa.gov/ Thanks to Acral for the comparative information and for the update ! ================================================== ======= "THIS IS NOT AN OFFICIAL ADVISORY.

HURRICANE DEAN UPDATE - 05:30 Hrs USA CDT August 22, 2007
As Hurricane Dean made landfall in Mexico's Yucatan Penninsula on Tuesday, it encountered a mountainous region that shut down it's energy source; namely the warm Caribbean waters. Hurricane Dean emerged into the Bay of Campeche (Southern Gulf of Mexico) as a weak Category 1 storm with top winds at only 80 miles per hour. While some strengthening is possible before it's landfall into east central Mexico, the extreme winds that once accompanied this hurricane are all but gone. Significant rainfall and a 6 foot storm surge will be felt at landfall later today. Some flooding is anticipated in the general area of east central Mexico. Since this hurricane is no longer a threat to US coastal areas, this will be our final SCHEDULED update for Hurricane Dean. We may post additional details at a later time. PLEASE NOTE: We are closely watching a Tropical low pressure area between Haiti and Jamaica. This low pressure area has potential to strengthen and we will post data concerning it if it becomes an area of more interest. For up to the minute Tropical System information, please use the NOAA link below. http://www.nhc.noaa.gov/ ================================================== ======= "THIS IS NOT AN OFFICIAL ADVISORY.

HURRICANE DEAN - Final Recap August 23, 2007
Hurricane Dean was a record setter. It was one of the fastest-ever forward moving hurricanes that achieved major hurricane status and it was one of only a few hurricanes in recorded history that made landfall as a Category 5 storm. This deadly storm was responsible for over a dozen deaths in 4 countries and that toll is expected to climb as searchers get into additional remote locations. The remnants of Dean are dissipating in the mountains of east central Mexico. Flooding has taken place in that region and authorities are dealing with the aftermath. This is our final message concerning Hurricane Dean. We are watching two low pressure waves in the Atlantic and Caribbean and will post information if necessary as things develop. http://www.nhc.noaa.gov/ ================================================== ======= "THIS IS NOT AN OFFICIAL ADVISORY.
