Overview

Tropical Storm Ingrid was a brief and relatively weak tropical cyclone in the Atlantic basin that existed from September 12 to September 17, 2007. It was designated the ninth named storm of the 2007 Atlantic hurricane season. Ingrid developed from what the National Hurricane Center identified as Tropical Depression Eight and did not intensify into a long-lived or powerful system before dissipating over the open ocean.

Meteorological history

The disturbance that became Ingrid organized into Tropical Depression Eight in mid-September and later attained tropical storm status as convection increased briefly. At the same time another nearby system, Tropical Depression Nine, organized and intensified more rapidly to become Hurricane Humberto, taking the next name on the list before Eight could be named. Ingrid remained separated from land throughout its lifecycle and tracked over the central to eastern Atlantic, where hostile environmental conditions arrested its development.

Characteristics and weakening factors

Ingrid was characterized by limited deep convection and a compact wind field. Persistent vertical wind shear — differences in wind speed and direction with height — hindered the storm's ability to maintain organized thunderstorms and a well-defined core. As a result, the system's sustained winds stayed at modest tropical-storm strength for only a short period before it lost tropical characteristics and dissipated.

Impacts and observations

Although Ingrid did not make landfall, it produced periods of enhanced showers and gusty winds in some eastern Caribbean islands. Meteorological reports noted rainfall associated with the system on islands such as Saint Martin and Antigua. These effects were localized and relatively minor compared with those of stronger storms, and the cyclone dissipated without causing widely reported damage or fatalities.

Timeline and notable points

  • Formed from Tropical Depression Eight on or about September 12, 2007.
  • Named Tropical Storm Ingrid while over the central/eastern Atlantic; short-lived as a tropical storm.
  • Lost organization due to strong wind shear and dissipated by September 17.
  • Coexisted briefly with Tropical Depression Nine, which became Hurricane Humberto.

Context and distinctions

Tropical Storm Ingrid (2007) is one of several tropical cyclones named Ingrid in different years and basins; it is distinguished by its short lifespan and limited impacts. It serves as an example of storms that form during the peak months of the Atlantic season but are prevented from intensifying by hostile atmospheric conditions.
