Tropical Storm GERT: Atlantic Cyclone That Regenerated Twice

Tropical Storm GERT formed on 19 August 2023 from a tropical wave that moved westward from the African coast into the Atlantic Ocean. The cyclone later weakened and regenerated after maintaining a persistent circulation over open waters. GERT caused no fatalities or damage. The storm reached peak intensity on 3 September with maximum sustained winds of 50 knots before dissipating on 4 September.

From Wave to Storm: How GERT Defied Forecast Models

GERT originated from a tropical wave that departed the west coast of Africa on 14 August 2023. The disturbance gradually organized and became a tropical depression on 19 August over the tropical Atlantic near 14.7°N, 46.6°W. During the following days, the system moved through an environment that limited development, with convection fluctuating around the circulation center.

By late August, GERT weakened significantly and degenerated into a surface trough on 26 August. The remnants continued drifting east of the Lesser Antilles while maintaining a low-level circulation and intermittent thunderstorm activity. The system remained identifiable despite losing tropical cyclone status, allowing meteorologists to continue monitoring its structure.

GERT regained tropical cyclone characteristics on 31 August north of the Leeward Islands and strengthened into a tropical storm on 1 September. The regeneration phase occurred while the system interacted with a complicated atmospheric pattern involving nearby tropical cyclones Franklin, Jose, and Idalia. The small size of the circulation and changing steering currents created challenges for predicting the storm’s redevelopment and future movement.

Although GERT did not affect coastal regions of East Asia, including China, the Philippines, Japan, or Vietnam, its behavior provided useful data for international tropical cyclone research. Such regeneration cases offer valuable data for improving forecasting techniques used by meteorological agencies worldwide.

GERT remained classified as a tropical storm under the Saffir-Simpson Hurricane Wind Scale and never reached hurricane intensity. Its track stayed over open Atlantic waters, keeping significant coastal impacts away from populated areas.

Peak Intensity Over Open Waters: GERT's 50-Knot Maximum

After regeneration, GERT strengthened briefly over the subtropical Atlantic. The cyclone reached its maximum intensity from 0000 UTC to 1200 UTC on 3 September, with maximum sustained winds of 50 knots, equal to approximately 92 km/h. Its minimum central pressure was estimated at 998 mb during this peak phase.

The intensity estimate was supported by satellite-based analysis, objective intensity techniques, and scatterometer wind retrievals. These observations showed that GERT developed a better-organized circulation while remaining far from land. The storm’s strongest winds occurred over the ocean, where no direct impacts to coastal communities were recorded.

After reaching peak strength, GERT began weakening as environmental conditions became less supportive. The cyclone moved northeastward over the Atlantic and gradually lost tropical characteristics. By 4 September, the system had weakened to a tropical storm with winds near 40 knots before dissipating near 39.4°N, 50.8°W.

The final best-track record for Tropical Storm GERT covers the period from 19 August to 4 September 2023. The storm’s lifecycle included initial development, degeneration into a remnant circulation, redevelopment into a tropical cyclone, and final dissipation over open water. Its 50-knot peak intensity and 998 mb minimum central pressure remain the defining measurements of the 2023 storm record.
