Season summary

The season's activity was reflected with a high cumulative accumulated cyclone energy

Accumulated cyclone energy is a measure used by the National Oceanic and Atmospheric Administration to express the activity of individual tropical cyclones and entire tropical cyclone seasons, particularly the North Atlantic hurricane season. It uses an approximation of the energy used by a...

 (ACE) rating of 177. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. ACE is only calculated for full advisories on tropical systems at or exceeding 34 knots (39 mph, 63 km/h) or tropical storm strength.

Tropical Depression Two

This depression formed from a tropical wave that was tracked from the coast of Africa on 20 June. As the wave moved into the extreme western Caribbean on 30 June, a broad cyclonic turning was noted. The system moved over the Yucatan peninsula on 1 July, and a weak low pressure area entered the Bay of Campeche early on 2 July. Later that day, deep convection became more organized over the extreme southwest Gulf of Mexico. A ship reported northwesterly winds of about 30 mph (48.3 km/h), which indicated the development of a tropical depression

Along the Texas coastline, Bret threatened several cities, resulting in the evacuation of 180,000 residents. Numerous shelters were opened throughout the region and prisons were evacuated. In nearby Mexico, roughly 7,000 people evacuated the coastline ahead of the storm. Bret made landfall in a sparsely populated region, resulting in relatively little damage in comparison to its intensity. Nevertheless, seven people were killed by the storm, four in Texas and three in Mexico. Most of the deaths were due to car accidents caused by slick roads. In all, the storm caused $15 million (1999 USD; $  USD) in damages.

Hurricane Cindy

On August 18, a tropical wave

 moved westward off the coast of Africa. With low pressures and gradually organizing convection, the wave spawned Tropical Depression Four in the eastern Atlantic. Initially it failed to intensify due to wind shear, and the center became ill-defined and difficult to locate on August 20. After passing south of Cape Verde, the depression intensified into Tropical Storm Cindy as the convection became concentrated around the center. Because of a strong ridge to its north, Cindy moved generally westward at first, though by August 21 it turned to the northwest as the ridge began to weaken. Banding features gradually increased as outflow improved, and late on August 21, Cindy was upgraded to a hurricane.

After reaching hurricane status, an increase in wind shear caused the center to be sheared from the convection, and Cindy quickly weakened to a tropical storm. Nearly two days later, high wind shear remained as the winds decreased to 60 mph (96.6 km/h). The shear decreased on August 24, and the convection increased over the center. By late on August 25, Cindy regained hurricane status. A ragged eye appeared on satellite imagery on August 27, and early on August 28 it attained major hurricane status. Cindy turned north-northwestward, now showing a well-defined eye
Eye (cyclone)

, and reached category 4 intensity with winds of 140 mph (220 km/h). Turning northward, the storm remained at peak intensity until August 30 when wind shear became prominent again, and Cindy began to weaken. On August 31, Cindy was downgraded to a tropical storm, and later that day it merged with a large extratropical storm northwest of the Azores

. There were no reports of damage or fatalities.

Hurricane Dennis

Dennis was traced to a tropical wave moving off the African coast on August 17. Moving west-northwestward, the wave strengthened into a tropical depression on August 23, and then into a tropical storm the following day. Located at the eastern end of an elongated trough, Dennis was affected by westerly shear. Despite the unfavorable conditions, the storm intensified, and reached hurricane status on August 26 over the Bahamas. Due a trough, Dennis moved very erratically. After passing through the Bahamas, Dennis entered an area more favorable for intensification, and strengthened into a Category 2 hurricane on August 28. A trough brought Dennis north and northeastward, causing it to parallel the Florida

 coastlines. While east of Florida Dennis reached its peaked as a Category 2 hurricane, though the wind field never resembled a classical tightly wound hurricane. The eyewall was around 35 miles (56.3 km) wide at its height. Dennis weakened as it continued northeastward, but still brought hurricane force winds to the North Carolina coast on August 30.

Hurricane Dennis eventually became involved with a cold front, causing vertical shear and cool, dry air to impact the circulation. A ridge of high pressure to its north caused Dennis to stall, leading the cyclone to weaken to a tropical storm on September 1 over the unfavorable conditions. Dennis soon strengthened again as it turned to the west-northwest, and made landfall near Harkers Island, North Carolina

Tropical Storm Emily

The origins of Emily were from a tropical wave that moved off of the African coast in mid-August, which was in a series of tropical waves that also spawned Hurricanes Cindy and Dennis. As the wave continued westward, an area of convection developed along it, which gradually organized. It is estimated it developed into a tropical depression at 0600 UTC on August 24, although advisories were not issued at the time. Within six hours, the depression intensified into a tropical storm, and later that day Hurricane Hunters

 confirmed its development. On the first advisory, the National Hurricane Center named the system Emily, and with winds estimated at 65 mph (105 km/h), the storm was forecast to attain hurricane status quickly.

The National Hurricane Center later discovered that the estimated winds in Emily were too high, and its peak winds were only 50 mph (85 km/h). Subsequently, it began a steady weakening trend due to increasing wind shear
Wind shear
Wind shear, sometimes referred to as windshear or wind gradient, is a difference in wind speed and direction over a relatively short distance in the atmosphere...

. It became very disorganized, weakening to minimal tropical storm intensity. Emily briefly restrengthened on August 27, although approaching Hurricane Cindy caused the system to weaken further. On August 28, the storm deteriorated to tropical depression status, and shortly thereafter Emily was absorbed by Hurricane Cindy. It never affected land.

Tropical Depression Seven

A strong monsoon-type flow interacted with a tropical wave in the Bay of Campeche. Early on September 5, satellite imagery indicated a well-defined low-level circulation in the Bay of Campeche. As a result, the system was classified as Tropical Depression Seven late on September 5. The NHC guidance computer model showed the depression heading north-northwestward. By 0000 UTC on September 6, the depression attained its peak intensity with maximum sustained winds of 35 mph (55 km/h) and a minimum barometric pressure of 1006 mbar (29.7 inHg). Shortly thereafter, the center of circulation of the depression became difficult to locate, but is was likely heading north-northwestward. Despite almost no deep convection and its close proximity to land, the SHIPS model predicted further intensification, due to warm sea surface temperatures.

At 1200 UTC on September 6, the depression made landfall near La Pesca, Tamaulipas
La Pesca, Tamaulipas

 with winds of 35 mph (55 km/h). The depression weakened while moving, and both radar and satellite noted only a poorly-defined center of circulation. As a result, the National Hurricane Center issued its final advisory of the depression at 1500 UTC on September 7. The intensity forecast predicted the depression would strengthen to a tropical storm shortly before landfall, as a result, the government of Mexico issued a tropical storm warning for Tampico to Matamoros, Tamaulipas

Tropical Depression Eleven

A tropical wave organized into Tropical Depression Eleven in the Bay of Campeche on October 4. Under weak steering currents, it drifted southward, then westward, remaining weak due to a broad surface trough over the eastern Gulf of Mexico. The depression merged with the trough on October 6, though tropical storm force winds remained over coastal waters. The depression's large, unorganized circulation, in combination with previous rainfall along the Mexican coastline, resulted in the worst flooding in at least 40 years for the region with at least 384 casualties attributed to the resulting flood.
