Ocean temperatures across the Caribbean are more than 1 degree Celsius above average, with Ocean Heat Content also significantly elevated, as Invest 98L approaches the region. The warm and deep ocean conditions present no immediate oceanic impediment to potential storm strengthening if atmospheric conditions, such as wind shear, become favorable. This information was detailed in an analysis posted to X by meteorologist Andy Hazelton on October 19th, 2025, at approximately 7:02 PM UTC. Hazelton noted that the entire region Invest 98L could traverse is registering temperatures of 30 degrees Celsius or higher. He further stated that the ocean's heat content is deep, suggesting that even a slow-moving or stalling storm would take a considerable amount of time to upwell cooler water, a factor that typically limits storm intensity. The analysis highlights that oceanic conditions are currently conducive to storm development. The meteorologist indicated that he had previously refrained from reporting on Caribbean ocean conditions due to the lack of a significant storm disturbance. However, with Invest 98L's approach, the elevated ocean temperatures and heat content have become a relevant factor in assessing potential storm development and intensity.
