Hurricane Kate was a late-season hurricane that attained hurricane status at a high latitude in November 2015. It was the eleventh and final named storm and fourth hurricane of the below average 2015 Atlantic hurricane season. Forming from a tropical wave, Kate passed through the Bahamas with minimal impacts, and later strengthened into a hurricane along the Gulf Stream. Kate is notable for being a late-season Atlantic hurricane despite the presence of El Nino in the Pacific Ocean.

Meteorological History

Tropical Storm Kate on November 9, while located near the Bahamas

On October 30, 2015, a weak tropical wave exited the West African coast. The tropical wave struggled to develop in the tropical Atlantic due to unfavorable conditions typical of the time of year. However, on November 4, the National Hurricane Center (NHC) noted the possibility of the system developing into a tropical cyclone near The Bahamas. On November 8, convection rapidly increased with the tropical wave, and a small well-defined circulation developed. Around 18:00 UTC that day, it is estimated that Tropical Depression Twelve formed while located north of the Turks and Caicos Islands. In their tropical cyclone report for the cyclone, NHC noted that development from tropical waves in November is somewhat rare, but not completely unprecedented.

Twelve afters after forming, the depression strengthened into Tropical Storm Kate and tropical storm warnings were put up for parts of the Bahamas. With a small size, fairly low shear and located over record-warm waters, Kate began to strengthen. Kate steadily strengthened on November 9 and 10, and acquired hurricane status at 00:00 UTC on November 11. This made Kate the latest Atlantic hurricane since Hurricane Epsilon of the hyperactive 2005 Atlantic hurricane season.

After becoming a hurricane, Kate continued to strengthen, and it is estimated that it peaked in intensity around 12:00 UTC on November 11 with maximum sustained winds of 85 mph and a minimum pressure of 980 mbar. This peak intensity is based off a blend off the lower SAB and TAFB Dvorak estimates and the higher ADT estimates. Kate began to weaken after this time as it encountered strong shear and cooler sea surface temperatures. At 00:00 UTC on November 12, Kate transitioned into an extratropical cyclone. The post-tropical remnants of Kate were absorbed by another extratropical cyclone, which affected the United Kingdom.
