Tropical Storm Jose (2017) was a short-lived tropical cyclone in the central Atlantic Ocean during the 2017 Atlantic hurricane season that formed from a tropical wave and briefly attained tropical storm strength before degenerating into a remnant low. The system developed near the Leeward Islands and produced heavy rainfall across parts of the Greater Antilles and northern South America, contributing to localized flooding and landslides. Jose's lifecycle was brief but notable for its interactions with nearby systems such as Hurricane Irma, Hurricane Jose (2017)—note: separate name usage—and regional weather features including the Intertropical Convergence Zone and an associated upper-level trough.

Meteorological history

A tropical wave that moved off the coast of Africa tracked westward across the Atlantic Ocean and entered the eastern Caribbean by late August 2017, interacting with the Intertropical Convergence Zone and a mid-level trough. Convective organization increased as the disturbance approached the Leeward Islands, aided by warm Atlantic sea surface temperatures and moderate low-level vorticity. On September 5, the system acquired a well-defined low-level circulation northeast of the Leeward Islands and the National Hurricane Center began advisories, classifying it as a tropical storm based on satellite intensity estimates and scatterometer data.

Jose's structure exhibited a small radius of maximum winds with deep convection concentrated east of the center; environmental wind shear from an upper-level trough displaced convection and inhibited intensification. The storm moved west-northwestward under the influence of a subtropical ridge anchored near the central Atlantic, passing near the northern Leeward Islands and approaching the northern coast of Venezuela and Colombia. By September 6, increasing southwesterly shear and entrainment of dry air eroded convective bands, and reconnaissance and satellite fixes indicated weakening to a tropical depression. The system degenerated into a remnant low late on September 7 as it moved over the extreme southwestern Caribbean Sea and later dissipated south of Hispaniola.

Preparations and warnings

As the system organized, meteorological agencies issued tropical storm warnings and watches for portions of the Leeward Islands, United States Virgin Islands, and the northern coasts of Venezuela and Colombia. Local authorities in Puerto Rico coordinated with the Federal Emergency Management Agency and activated municipal emergency operations centers to prepare for heavy rainfall, flash flooding, and mudslides. Ports in affected territories, including facilities in San Juan, Puerto Rico and Ponce, Puerto Rico, monitored advisories from the National Oceanic and Atmospheric Administration and adjusted ferry and shipping schedules.

Governors and municipal leaders in islands such as Saint Kitts and Nevis, Antigua and Barbuda, and Barbados issued public advisories urging residents to secure property, obtain emergency supplies, and avoid riverbanks and coastal areas prone to storm surge. Airlines adjusted flight schedules for airports including Luis Muñoz Marín International Airport and Tocumen International Airport to accommodate anticipated disruptions. Humanitarian organizations with regional presence, including the International Red Cross and Red Crescent Movement and local non-governmental organizations, pre-positioned relief materials and coordinated with national disaster offices.

Impact and aftermath

Although Jose remained relatively weak, it produced torrential rains across parts of northern South America and the Greater Antilles, triggering flash floods and landslides in mountainous terrain. In coastal Venezuela, the storm's outer bands resulted in flooding of low-lying communities and localized infrastructure damage. In Colombia, heavy precipitation led to overflow of rivers in the Guajira Peninsula, prompting temporary evacuations. Puerto Rico experienced scattered downpours and minor urban flooding; the island, still recovering from the impacts of Hurricane Maria (2017), saw localized exacerbation of existing storm damage but no large-scale collapse of critical infrastructure.

A number of roads were temporarily impassable across the Windward and Leeward Islands due to mudslides and fallen trees, and emergency services conducted search-and-rescue operations in isolated cases. Maritime interests reported elevated seas and dangerous rip currents across the eastern Caribbean and along the northern coasts of South America, resulting in advisories from coastal authorities. Fatalities associated with Jose were reported in localized incidents linked to flooding and landslides, and total economic damages were assessed as limited compared with the major cyclones of the 2017 season.

In the storm's aftermath, regional disaster response agencies coordinated cleanup, debris removal, and infrastructure repairs. International relief organizations assisted with temporary sheltering and restoration of utilities where needed. Meteorological services continued to monitor the remnant low and downstream effects on rainfall distribution across the Caribbean, issuing flash flood warnings where prolonged showers persisted.

Records and significance

Jose was one of several tropical cyclones to form during the hyperactive 2017 Atlantic hurricane season, which included notable systems such as Hurricane Harvey (2017), Hurricane Irma (2017), and Hurricane Maria (2017). Although Jose's peak intensity was modest, its rapid lifecycle and interactions with regional features provided case studies for tropical cyclone formation from African easterly waves and the influence of vertical wind shear on small cyclones. The storm underscored the vulnerability of Puerto Rico and parts of Venezuela and Colombia to heavy rainfall events even from short-lived systems, informing subsequent improvements in early warning dissemination by agencies like the National Weather Service and national meteorological institutes.

Scientifically, Jose contributed to observational datasets used in post-season analyses by organizations including the National Hurricane Center, NOAA, and regional climate centers studying storm clustering during the 2017 season. Its occurrence amid several major hurricanes highlighted challenges in resource allocation and emergency management during concurrent disasters, prompting review of preparedness protocols by emergency management entities across the Caribbean and northern South America.
