#HURRICANE TRACK DATA UPGRADE#

Bathymetry and Topology data from the School of Ocean and Earth Science and Technology, The University of Hawaii at Manoa was converted from a NetCDF raster grid to contours.NEXRAD II Radar messages downloaded from Amazon S3 and converted to geojson using the NOAAвЂ™s Weather and Climate Toolkit.Last yearвЂ™s record-breaking season serves as a reminder to all residents in coastal regions or areas prone to inland flooding from rainfall to be prepared for the 2021 hurricane season.The visualization comprises of three sources:

New drones will be launched from NOAA Hurricane Hunter aircraft that will fly into the lower part of hurricanes, and in the ocean, saildrones, hurricane gliders, global drifters, and air-deployable technology - called ALAMO floats - will track various parts of the life cycle of tropical storms. NOAAвЂ™s Atlantic Oceanographic and Meteorological Laboratory will deploy its largest array of air and water uncrewed systems to gather data designed to help improve hurricane intensity forecasts and forecast models.

#HURRICANE TRACK DATA UPGRADE#

This upgrade extends the lead time of P-Surge forecast guidance from 48 to 60 hours in situations where there is high confidence. Forecasters at the National Hurricane Center are now using an upgraded probabilistic storm surge model - known as P-SurgeВ - which includes improved tropical cyclone wind structure and storm size information that offers better predictability and accuracy.Additionally, Global Positioning Satellite Radio Occultation (GPS-RO) data are now included in the GFS model, providing an additional source of observations to strengthen overall model performance. In March, NOAA upgraded the flagship Global Forecast System (GFS) to improve hurricane genesis forecasting and coupled GFS with a wave model extending ocean wave forecasts from 10 days out to 16 days.In an effort to continuously enhance hurricane forecasting, NOAA made several updates to products and services that will improve hurricane forecasting during the 2021 season. вЂњThe forecasters at the National Hurricane Center are well-prepared with significant upgrades to our computer models, emerging observation techniques, and the expertise to deliver the life-saving forecasts that we all depend on during this, and every, hurricane season.вЂќ вЂњAlthough NOAA scientists donвЂ™t expect this season to be as busy as last year, it only takes one storm to devastate a community,вЂќ said Ben Friedman, acting NOAA administrator.

вЂњPredicted warmer-than-average sea surface temperatures in the tropical Atlantic Ocean and Caribbean Sea, weaker tropical Atlantic trade winds, and an enhanced west African monsoon will likely be factors in this yearвЂ™s overall activity.вЂќ Scientists at NOAA also continue to study how climate change is impactingВ the strength and frequency of tropical cyclones. вЂњENSO-neutral and La Nina support the conditions associated with the ongoing high-activity era,вЂќ said Matthew Rosencrans, lead seasonal hurricane forecaster at NOAAвЂ™s Climate Prediction Center. Д®l Nino Southern Oscillation (ENSO) conditions are currently in the neutral phase, with the possibility of the return of La Nina later in the hurricane season.
