Atlantic Tropical Weather Discussion — 2025-12-19 09:02 EST
Overview
As of the morning of December 19, 2025, a 1014 mb low near 30N55W in the central Atlantic is producing gale-force winds and very rough seas. A weakening cold front extends southwest from the low through 24N56W, with associated convection and strong wind fields. A separate cold front traverses the Gulf of Mexico from the Florida Panhandle to northeast Mexico, while trade winds dominate much of the Caribbean.
Regional Highlights
- Gulf of Mexico: Fresh to strong northerly winds are occurring behind a cold front extending from the Florida Panhandle to northeast Mexico. Seas are moderate, reaching up to 6 ft, with isolated showers ahead of the front affecting southeastern and southwestern Gulf waters.
- Caribbean: Fresh to strong trade winds continue offshore northwest Colombia with seas of 6–8 ft. Moderate to fresh trades and 4–6 ft seas prevail across the central and eastern basin. Elsewhere, winds are moderate or weaker with slight seas.
- Western Atlantic: The low near 30N55W is generating northeast gale-force winds within 90 nm of its northwest quadrant and producing seas of 12–17 ft north of 27N between 53W–59W. A shear line follows to the southern Bahamas. Scattered heavy showers are observed near the low and ahead of the cold front. Fresh to strong southerly winds and seas up to 10 ft extend north of 28N to near 71W. Additional scattered showers affect waters near central and northeast Florida.
Marine Conditions
- Winds: Gale-force northeast winds near 30N55W in the Atlantic; fresh to strong northerly winds in the northwest Gulf; fresh to strong trades off northwest Colombia and across parts of the Caribbean.
- Seas: 12–17 ft in central Atlantic between 53W–59W north of 27N; up to 10 ft near 28N–71W; 6–8 ft near northwest Colombia; 4–6 ft across central and eastern Caribbean; up to 6 ft in the northwest Gulf.

Catastrophic
*Tropical Depression (TD)
A tropical cyclone with maximum sustained winds of less than 39 mph. While not a hurricane, it’s a precursor stage that can develop into a more severe storm.
Category 1
Very dangerous winds will produce some damage: Well-constructed frame homes could have damage to roof, shingles, vinyl siding and gutters. Large branches of trees will snap and shallowly rooted trees may be toppled.
Category 2
Extremely dangerous winds will cause extensive damage: Well-constructed frame homes could sustain major roof and siding damage. Many shallowly rooted trees will be snapped or uprooted and block numerous roads.
Category 3
Devastating damage will occur: Well-built framed homes may incur major damage or removal of roof decking and gable ends. Many trees will be snapped or uprooted, blocking numerous roads. Electricity and water will be unavailable for several days to weeks after the storm passes.
Category 4
Catastrophic damage will occur: Well-built framed homes can sustain severe damage with loss of most of the roof structure and/or some exterior walls. Most trees will be snapped or uprooted and power poles downed. Fallen trees and power poles will isolate residential areas. Power outages will last weeks to possibly months.
Category 5
Catastrophic damage will occur: A high percentage of framed homes will be destroyed, with total roof failure and wall collapse. Fallen trees and power poles will isolate residential areas. Power outages will last for weeks to possibly months. Most of the area will be uninhabitable for weeks or months.
