TROPICAL STORM DEAN

Tropical Storm Dean off the Canadian Coastline

A large tropical wave crossed into the Atlantic Ocean from the coast of Africa on August 14. The wave moved west and gradually became more organized as it developed deep thunderstorms and convection. On August 22, a Hurricane Hunter flight found a closed circulation and the wave became Tropical Storm Dean to the north of Puerto Rico, skipping tropical depression status. Dean moved to the WNW through the Virgin Islands, and as it did so, it entered a hostile shearing environment, and rapidly degenerated into an open tropical wave on August 23 when no closed circulation could be found. The remnant wave of Dean rapidly chased to the north, and became involved with a trough on August 24, and developed a broad area of low pressure. The low moved very little on August 25, as convection began to develop near the center, and by August 26, there was enough convection to classify the storm as Tropical Depression Dean once again.

The depression became Tropical Storm Dean just hours later on August 27, and it strengthened further and reached a peak intensity on August 27 with winds of 70 mph and a pressure of 994 mbar. Dean moved over colder waters after this and weakened into an extratropical storm on August 28. No deaths were reported due to Dean, but there were damages reported in Puerto Rico due to heavy rains caused by the storm which flooded about 1200 homes.
