File:Hurricane Dennis on July 7 2005 1550 UTC.jpg

Summary

Description
English: Hurricane Dennis threaded its way between Jamaica and Haiti on a direct course for Cuba on July 7, 2005. The storm now has the distinctive hurricane form, with a well-defined eye surrounded by bands of swirling clouds. At 10:50 a.m. local time (15:50 UTC), when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite took this image, Dennis was just below a Category 3 hurricane, with winds of 175 kilometers per hour (110 miles per hour) and stronger gusts. Less than an hour before this image was taken, the storm's small dark eye was about 105 kilometers (65 miles) northeast of Kingston, Jamaica, and 170 kilometers (105 miles) south-southeast of Guantanamo, Cuba. The National Hurricane Centre reports that Dennis is traveling northwest at about 24 kilometers per hour (15 mph).

A storm of this size is a threat not just because of its powerful winds: Dennis is expected to produce heavy rain and coastal and inland flooding. Five to ten inches of rain may fall over Haiti, the Dominican Republic, Jamaica, Cuba, and the Cayman Islands, with as much as 15 inches falling in parts of Jamaica. Heavy rainfall can trigger flash floods and mudslides in mountainous regions. The storm will probably also raise tide levels by five to seven feet and generate large and dangerous waves.
Dennis is expected to strengthen as it moves north towards the Gulf Coast of the United States. For official storm warnings and additional information, please visit the National Hurricane Centre.

The image is available in additional resolutions from the MODIS Rapid Response Team.

Français : l' Ouragan Dennis trace sa voie entre la Jamaïque et Haiti et se dirige vers Cuba le 7 juillet 2005. La dépression a maintenant toutes les caractéristiques d'un cyclone, et en particulier un œuil bien défini. Au moment ou la photo a été prise, l'ouragan allait atteindre le niveau 3, avec des vents de 175 km/h. Une heure avant que la photo ne soit prise, l'œuil du cyclone était à mi-chemin entre Kingston, en Jamaïque et Guantanamo, à Cuba.

Les cyclones présentent une grande menace dans la zone caraibe non seulement à cause des vents violents, des grandes vagues qu'ils provoquent et des ondes de tempête; mais aussi des pluies diluviennes qui s'abbattent sur leur sillage (plus de 350 mm pour Dennis), et qui entrainent des crues brutales et des coulées de boue.
