Monitoring the recent evolution of storminess across both the Northern and Southern Hemisphere. Storm tracks are identified by tracking sea level pressure minima and the following pages highlight storm tracks and important related fields (precipitation, low-level wind vectors and magnitude, significant wave heights, and sea ice) for the past 10, 30, and 90 days. Storm tracks from the Global Forecast System (GFS) are also included.
