a. Synoptic History

Ana formed as a tropical depression from a frontal low pressure system just off the coast of South Carolina on 30 June. It moved slowly eastward and became a tropical storm with 46-mph sustained winds on the next day even as vertical wind shear limited convective development near the center of the low-level circulation. A deepening short-wave trough moved to eastern North America and accelerated the storm toward the northeast on the 2nd and 3rd. On 4 June, Ana became extra-tropical while moving over colder water and then dissipated. Ana did not affect land.

b. Meteorological Statistics

A USAF Reserve reconnaissance aircraft flew into Ana on the afternoon of 1 July and measured a 62-mph wind speed in the northeast quadrant at 1500 feet and a minimum surface pressure of 1000 millibars. These values are the basis for the maximum 1-minute surface wind speed of 46 mph and the minimum sea level.

c. Casualty and Damage Statistics

There were none.
