Tropical Storm Nadine: Rapid Intensification and Landfall in Belize
Tropical Storm Nadine formed in the western Caribbean on 19 October 2024 and became a brief yet destructive tropical storm before crossing Belize and weakening over Central America. The storm peaked near Belize City with maximum sustained winds of 50 kt, equivalent to 58 mph, and a minimum central pressure of 1000 mb at landfall. Nadine brought heavy rainfall, flooding, and tropical storm conditions to Belize, northern Guatemala, and southeastern Mexico before dissipating on 20 October. The storm’s remaining moisture later contributed to the formation of Tropical Storm Kristy in the eastern Pacific basin.
Formation Over Warm Caribbean Waters: Nadine’s Brief Track to Belize
Nadine originated from a broad low-pressure area that developed over the southwestern Caribbean Sea on 15 October 2024. The disturbance remained weak and disorganized while drifting northwestward near the coast of Nicaragua, producing scattered thunderstorms without a well-defined circulation center. By 17 October, convection increased and surface pressures began falling over the western Caribbean, allowing the system to gradually organize.
On 18 October, satellite observations showed a developing low-level circulation with stronger winds north of the center. Favorable atmospheric conditions, including warm sea surface temperatures, low vertical wind shear, and strong upper-level outflow, supported rapid organization. The National Hurricane Center classified the system as Tropical Storm Nadine at 0000 UTC on 19 October, when it was located about 160 nautical miles east of Belize City, Belize.
Nadine strengthened quickly as it moved westward across the northwestern Caribbean. A high-pressure ridge over the region steered the storm toward Belize, while warm waters helped sustain increasing thunderstorm activity around the circulation center. The storm’s structure improved as convection wrapped closer to the core and the radius of maximum winds contracted before landfall.
Belize authorities monitored the approaching storm through national weather and emergency channels. The National Emergency Management Organization of Belize activated preparedness protocols as tropical storm conditions threatened coastal communities, while forecasts emphasized heavy rainfall and flooding risks rather than extreme wind impacts.
The storm peaked in intensity at 1600 UTC on 19 October near Belize City. Nadine reached maximum sustained winds of 50 kt, or about 58 mph, with a central pressure of 1000 mb in the official best-track record. The peak occurred shortly before landfall, marking the strongest phase of a cyclone that developed and weakened within roughly 24 hours.
Landfall in Belize and Inland Decay: Heavy Rainfall Takes Center Stage
Nadine made landfall near Belize City, Belize, at approximately 1600 UTC on 19 October 2024 as a tropical storm. The cyclone crossed the coastline with strong winds and concentrated rain bands, affecting coastal areas and inland communities with periods of heavy precipitation.
The main hazard from Nadine was rainfall. Tropical moisture associated with the storm produced flooding across parts of Belize and neighboring regions, especially in areas vulnerable to rapid water accumulation. Emergency officials in Belize warned residents about flooding, road disruptions, and weather-related hazards as the storm moved inland.
After crossing Belize, Nadine continued westward into northern Guatemala. The storm quickly weakened because land interaction disrupted its circulation and removed the ocean heat source that had supported its development. By 0000 UTC on 20 October, Nadine had weakened to a tropical depression near northern Guatemala.
The weakening system then moved into southern Mexico, where its remaining moisture contributed to continued rainfall. Mexico’s weather authorities, including the National Meteorological Service (Servicio Meteorológico Nacional, SMN), tracked the system as it affected southeastern areas. Rainfall impacts extended across parts of the region, including areas where saturated ground increased flood risks.
The National Hurricane Center’s final assessment documented at least seven direct fatalities linked to Nadine’s impacts across Central America and southeastern Mexico. Additional indirect deaths were reported in Mexico, bringing the total reported fatalities across the region to at least 13.
Nadine’s Brief Lifespan: A Small Storm With Outsize Rainfall Impacts
Meteorologically, Nadine had a compact and rapid lifecycle. The storm developed from a weak Caribbean disturbance, strengthened into a tropical storm on 19 October, reached peak intensity before landfall, and dissipated over southern Mexico on 20 October.
The storm’s short duration did not prevent significant impacts because its rainfall-producing circulation affected areas with vulnerable terrain and communities exposed to flooding. Nadine’s strongest winds remained within tropical storm intensity, but its moisture transport created hazards far beyond the immediate coastline.
The system lost the oceanic heat and moisture needed to sustain itself after moving over land. Convection weakened, the low-level circulation became less defined, and Nadine transitioned into a remnant low over southern Mexico early on 20 October.
Although Nadine quickly disappeared as a tropical cyclone, its atmospheric remnants continued westward. Residual moisture and mid-level circulation energy moved into the eastern Pacific basin and contributed to the development of Tropical Storm Kristy on 21 October.
The final best-track position for Nadine was recorded near 17.1°N, 91.2°W at 0600 UTC on 20 October 2024, with maximum winds reduced to 25 kt before the circulation dissipated.
