Tropical cyclone development occurs worldwide, however one key issue that has plagued the maritime industry is the lack of a single global standard for tropical cyclone classification. There are several different agencies that oversee these regions, each with their own varied thresholds and naming methodology. 

Each agency utilizes different criteria in their naming of tropical systems, primarily related to a system’s strength. As storms move between regions, their classification can appear to change – even if their strength does not. This can create confusion when timing and decision-making matter the most. This is where WRI can primarily assist. We divide our tropical alerts into the four main ocean basins - Atlantic, East Pacific, West Pacific (including Southwest Pacific), and Indian Oceans. In rare cases, when there is a developing system in a region not covered by the zones, these are handles on a special case-by-case basis. Within these regions, we utilize a consistent classification and naming system to ensure that all alerts are clear and do not change if the system passes between basins.

Rather than relying on a single regional agency, WRI integrates data from leading global sources and our own in-house weather modeling to create clear and consistent guidance for our clients. Using advisories from the major forecasting centers, combined with our own analysis and expertise, we provide:

• Clear assessments of potential tropical storm development
• Expected intensity and track trends
• Model guidance interpretation and uncertainty
• Operational impacts to vessels and ports

As tropical systems evolve and develop, WRI delivers timely and clear tropical alerts and route recommendations to help clients make the most optimal and informed operational decisions. Whether it’s avoiding hazardous conditions at sea or anticipating port disruptions, our team ensures that we will communicate clearly with your vessels and land-based operations team to make you as prepared as possible for dangerous tropical scenarios.
