Chantal was a 69-mph tropical storm that developed just east of the Lesser Antilles, re-curved around the western periphery of the Atlantic subtropical high pressure ridge and became extratropical east of Newfoundland as it moved over the far north Atlantic Ocean.


a. Synoptic History

Chantal originated from a tropical wave which moved off of the coast of Africa on 5 July and soon showed signs of a low level cloud circulation. On the 12th, satellite imagery showed enough organization for the system to be upgraded to a tropical depression while it was located a few hundred miles east of the Lesser Antilles. An aircraft investigated on the 13th and confirmed the existence of a depression.

Even though there were signs of unfavorably strong upper level westerlies, the depression strengthened to a storm on the 14th, while centered a little over 200 nautical miles north-northeast of Puerto Rico. On the 15th, it threatened the southeast and central Bahamas as it was moving west-northwestward, but it gradually re-curved toward the north on the 16th and 17th and did not directly affect the Bahamas.

The storm's maximum 1-minute surface wind of 69 mph is estimated to have been reached on the 17th as it was moving northward between Bermuda and the U.S. mid Atlantic coast. Although there was a brief threat to Bermuda, the center passed well to the west of there on the 18th. Chantal turned toward the northeast and accelerated across the North Atlantic shipping lanes where it became extratropical on the 20th.

b. Meteorological Statistics

The storm was monitored by Air Force Reserve Unit reconnaissance aircraft from the 13th to the 18th. There were 40 penetrations into the center of the storm during this period, which averages to one fix every three hours. The lowest surface pressure reported from an aircraft was 991 mb at 2338 UTC on the 16th and the maximum wind speed was 77 mph at a flight level of 1500 feet a few hours earlier.

c. Casualty and Damage Statistics

No reports of casualties or damage have been received in connection with Chantal.
