Hurricane Oscar has emerged as a surprising force in the 2024 Atlantic hurricane season, rapidly intensifying from a tropical storm to a Category 1 hurricane on Saturday. The sudden escalation of Hurricane Oscar caught forecasters off guard, making it the 10th hurricane of the season and prompting warnings across the Caribbean. With maximum sustained winds reaching 85 mph and gusts even stronger, this small but powerful storm’s development highlights the challenges of predicting rapidly changing weather systems.
SURPRISE! We have a surprise hurricane. Four hours ago, Oscar didn’t even have a name. Now it’s an 80 mph Category 1.
How does this happen? Oscar is so remarkably small that it can gain and lose strength very quickly.

Hurricane Oscar’s Unexpected Formation
Just a day before it intensified, Hurricane Oscar was a tropical disturbance with minimal potential for development, according to the U.S. National Hurricane Center. However, early Saturday morning, satellite observations detected a well-defined inner core, leading to its classification as a hurricane by 2 p.m. ET. Oscar’s rapid growth was fueled by its compact size, which allowed it to strengthen quickly—something small tropical cyclones are known for.
Small storms like Hurricane Oscar present unique forecasting difficulties because their tiny cores can respond swiftly to environmental conditions. In Oscar’s case, hurricane-force winds extend just six miles from the center, with the eye itself being only three miles wide, making it one of the smallest hurricanes on record. This compact nature allowed it to defy earlier predictions and rapidly intensify into a significant weather event.
Impacts of Hurricane Oscar on the Caribbean
The sudden development of Hurricane Oscar led to urgent hurricane warnings for the Turks and Caicos Islands and the southeastern Bahamas. The storm was located just five miles south of Grand Turk as of Saturday evening, and its tight, well-defined core posed a threat to the islands. In response, Cuba issued hurricane watches for the Guantanamo, Holguin, and Las Tunas provinces as the storm drifted toward its northeast coast.
Forecasters anticipate that Hurricane Oscar could strengthen further, potentially reaching Category 2 status before encountering upper-level winds that may weaken it by early next week. The hurricane’s small but intense core could cause dangerous conditions, including strong winds, heavy rainfall, and coastal impacts in the affected areas.
Hurricane Oscar Sets Records in the 2024 Season
Hurricane Oscar’s formation adds to the already active 2024 hurricane season, which has now seen 10 hurricanes. The period from September 24 to October 19 saw eight named storms, breaking a record for most named storm formations in that time frame, a record that had stood since 1950. Oscar’s appearance comes shortly after Hurricane Milton, which caused significant damage and loss of life in Florida.
The 2024 season’s activity underscores the unpredictability of hurricanes, with Hurricane Oscar serving as a prime example of how quickly conditions can change. This season has already produced five hurricanes that impacted the Gulf Coast, and experts suggest that one or two more storms could develop before the season officially ends on November 30.
The Science Behind Hurricane Oscar’s Rapid Intensification
Meteorologists were particularly surprised by Hurricane Oscar’s sudden strengthening because the storm showed little indication of intensifying rapidly beforehand. On Friday, forecasters gave the tropical disturbance a low chance of development. However, within just over three hours, the system evolved into an 80 mph hurricane, surpassing the rapid intensification record set by Hurricane Humberto in 2007.
Oscar’s compact size is a key factor behind its swift growth. Small hurricanes like Oscar can take advantage of favorable atmospheric conditions more efficiently than larger storms. Their rapid intensification often eludes computer forecast models, which use grid-based predictions that may miss critical details about smaller systems. This forecasting challenge is why Hurricane Oscar’s quick formation caught experts by surprise.
Path and Future of Hurricane Oscar
Currently, Hurricane Oscar is projected to shift its path toward the northeast coast of Cuba before turning northward. A strong cold front is expected to introduce dry air and high-altitude winds that will likely weaken the storm starting on Monday, with further weakening anticipated by Tuesday. Although the storm is expected to dissipate by the middle of the week, it could still cause prolonged periods of large swells affecting U.S. East Coast beaches.
Meanwhile, Tropical Storm Nadine, another storm in the region, made landfall in Belize on Saturday. With winds of 50 mph, Nadine brought heavy rainfall to parts of northern Guatemala, Belize, and Mexico’s Yucatán Peninsula. Although the storm is expected to dissipate by early Sunday, significant rainfall could lead to localized flooding and landslides in affected areas.
The 2024 Hurricane Season’s Ongoing Threat
Hurricane Oscar’s emergence adds to the ongoing activity of the 2024 hurricane season, which remains unpredictable. While the tropics may temporarily calm down following Oscar and Nadine, late-season storms are still possible, especially in October and early November.
The case of Hurricane Oscar serves as a reminder of the challenges in predicting tropical cyclone behavior, particularly for small and rapidly evolving systems. With its sudden intensification and compact structure, Hurricane Oscar exemplifies the volatility of the 2024 season, highlighting the need for constant vigilance and preparation in hurricane-prone areas.
