Hurricane Humberto, the third hurricane and the eighth named storm of the Atlantic season, is currently located about 200 miles NNE of Bermuda, moving towards the northeast at about 20 mph. Humberto is a Category 3 hurricane on the Saffir-Simpson scale, with maximum sustained winds of around 115mph and higher gusts.
Over the next 24 hours Humberto is expected to continue moving in the same direction, gradually weakening as it goes. It is then expected to turn NNE, slowing down before turning ENE as it swings around the southwest flank of a trough of low pressure, and weakening further as it encounters an area of strong shear. It will then continue towards the ENE as it becomes entrained into the mid-latitude flow and starts to track across the Atlantic as an ex-hurricane.
Humberto has been keeping a respectable distance from the east coast, moving north at a relatively slow speed. This has given it the opportunity to generate a pulse of longer-lasting swell for many spots.
Forecast: New Jersey and New York
In North Carolina, for example, wave heights are already around six feet, with strong northwest winds. Conditions improve on Friday with the possibility of very good quality, largish surf, which steadily decreases over the weekend. Further north in New York and New Jersey, and up into Nova Scotia, some largish surf and clean conditions are also expected on Friday, dropping on Saturday.
