Kate intensified into the fourth Atlantic hurricane of 2015 as it raced northeastward.  At 10:00 a.m. EST on Wednesday the center of Hurricane Kate was located at latitude 36.8°N and longitude 60.5°W which put it about 395 miles (635 km) northeast of Bermuda and about 780 miles (1160 km) south-southwest of Cape Race, Newfoundland.  Kate was moving toward the northeast at 45 m.p.h. (72 km/h).  The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h).  The minimum surface pressure was 985 mb.

The organization of Hurricane Kate improved on Wednesday when a partial eyewall wrapped around the northern and western sides of the center of circulation.  The structure of Kate is somewhat tilted toward the northeast by stronger southwesterly wind in the upper levels of the atmosphere.  However, Kate currently has a warm core and it is still a tropical cyclone.  Kate is moving over water where the Sea Surface Temperature (SST) is near 25°C.  In a day or so the effects of strong vertical wind shear and cooler SSTs will cause Hurricane Kate to begin a transition to an extratropical cyclone.

Strong westerly winds are steering Kate rapidly toward the northeast and that general motion is expected to continue during the next few days.  Kate could approach the United Kingdom as a strong extratropical cyclone during the weekend.
