Understanding Hurricane Tracking and Forecasting
Hurricane tracking and forecasting are crucial for predicting the path and potential impact of these powerful storms. The National Hurricane Center (NHC) provides critical data and updates on hurricane activity, including tracking maps, intensity charts, and wind arrival tables. These tools help experts and the general public alike stay informed and prepared for the potential consequences of a hurricane.
The tracking map, for instance, shows probabilities of at least 5 percent, with forecast data available for up to five days. This information is essential for identifying areas that may be affected by the storm. Additionally, the intensity chart provides the best track and forecast path, allowing for a more detailed understanding of the storm’s potential impact. The NHC’s data is also used to generate wind arrival tables, which predict the arrival times of sustained, damaging winds of 58 m.p.h. or more for select cities.
Data Sources and Methodology
The data used to create these tracking and forecasting tools comes from various sources, including the National Oceanic and Atmospheric Administration (NOAA), the U.S. Census Bureau, and Natural Earth. The wind arrival tables, for example, are generated from a New York Times analysis of NHC data, using geographic locations from the U.S. Census Bureau and Natural Earth, and time zones based on Google. The radar map, on the other hand, uses radar imagery from NOAA via Iowa State University, combining individual radar stations that comprise the NEXRAD network.
Other tools, such as the storm surge map and rip currents map, rely on data from the NHC. The storm surge map forecasts potential flooding areas along the United States Gulf and Atlantic coasts, Puerto Rico, and the U.S. Virgin Islands, taking into account tides but not waves or rainfall-induced flooding. The rip currents map shows the risk of rip currents, which is not always associated with active tropical cyclones.
Additional Resources and Visualizations
Further visualizations, such as the satellite map and precipitation map, provide additional insights into the storm’s activity. The satellite map uses imagery from NOAA and the Japanese Meteorological Agency via the Cooperative Institute for Research in the Atmosphere, while the precipitation map relies on data from the National Weather Service and NOAA. The historical map, which shows storm paths from the NOAA’s HURDAT database, offers a broader context for understanding hurricane activity in the region.
These resources and tools are essential for understanding and preparing for hurricanes. By providing accurate and up-to-date information, they help save lives and reduce the impact of these powerful storms.
