Seasonal forecast and summary

Dr. William M. Gray of Colorado State University issued forecasts on May 29 and July 28 indicating within both forecasts the anticipation of a below normal hurricane season. In May, a total of 8 named tropical storms were expected, with four hurricanes expected, 15 days with hurricanes, and a total of 35 days with a tropical storm active in the northern Atlantic Ocean. In July, the numbers were dropped to a total of 7 named storms, 4 hurricanes, 10 hurricane days, and 25 days with a named tropical storm, which almost perfectly verified. The season's activity was reflected with a cumulative accumulated cyclone energy (ACE) rating of 36, which is classified as "below normal". 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

Tropical Depression Three

The third tropical depression of the season was detected early on July 27 in the open waters of the Atlantic, north of

A tropical disturbance was detected on August 4 in the northwestern Gulf of Mexico along the lower Texas coast. The low-pressure system moved slowly toward land, limiting the system's development. On August 5, the system became organized enough to be considered a tropical depression. The storm moved inland overnight, dumping several inches of rain over South Texas and causing street flooding in Brownsville and nearby

in the previous year. The third tropical storm and second hurricane of the season, Charley formed as a subtropical low on August 13 along the Florida panhandle. A few days later intensified it into a tropical storm off the coast of South Carolina, and Charley attained hurricane status before moving across eastern North Carolina. It gradually weakened over the north Atlantic Ocean before transitioning into an extratropical cyclone, though its remnants remained identifiable for over a week until after crossing the British Isles and dissipating on August 30. The storm brought light to moderate precipitation along its path through the southeastern United States. In Georgia and South Carolina, the rainfall alleviated drought conditions. In North Carolina, where the hurricane made landfall, tidal flooding and downed trees were the primary impact. The storm brought high winds to southeastern Virginia, where 110,000 people were left without power. Minor damage extended along the Atlantic coastline northward through Massachusetts. One traffic fatality was reported each in North Carolina and Virginia. Three people in Maryland died due to a plane crash related to the storm. Throughout the United States, Hurricane Charley caused an estimated $15 million in damage (1986 US$, $29 million 2008 USD). As an extratropical cyclone, Charley brought heavy rainfall and strong winds to Ireland and the United Kingdom, causing at least 11 deaths. In Ireland, the rainfall set records for 24‑hour totals, including an accumulation of more than 7.8 in (200 mm) which set the record for the greatest daily rainfall total in the country. In the country, the rainfall caused widespread flooding, resulting in two rivers overflowing their banks. In the Dublin area, 451 buildings were flooded, some up to a depth of 8 ft (2.4 m). In the United Kingdom, the storm caused downed trees and power lines, as well as flooded rivers.

Tropical Depression Five

This tropical depression formed in the eastern tropical Atlantic Ocean on August 31. The depression moved west-northwest, then northwest away from the Caribbean Sea without further development before dissipating east-southeast of

on September 4.

Tropical Depression Six

A tropical wave crossed the Caribbean sea, moving into a favorable upper environment in the western Caribbean sea on August 31. The system formed into a weak tropical depression before crossing the Yucatán peninsula, becoming better organized as it moved into the south-central and western Gulf of Mexico between September 1 and 3. The system moved ashore east-central Mexico before quickly dissipating as a tropical cyclone on September 4. Satellite imagery revealed that its residual cloud pattern persisted over Mexico for an additional couple of days before degenerating. Heavy rainfall fell primarily north of its track, with the maximum across northeast Mexico falling at El Barranco/Altamira, where a total of was measured.
