Update: Hurricane Katia

Posted at 11:51 AM ET

katia-3-smallHurricane Katia is currently located approximately 540 miles (870 kilometers) south of Bermuda, according to the National Hurricane Center (NHC). The storm currently packs sustained winds of around 110 mph (175 kmph), equivalent to a category 2 hurricane. Katia is traveling in a northwest direction and is expected to maintain this general motion for the next 48 hours. The NHC said hurricane force winds extend 60 miles (95 kilometers) from the center of the storm while tropical storm force winds extend 205 miles (335 kilometers).

Katia is expected to continue to move across the Atlantic in a northwesterly direction over the next day or two on a track that brings it to the southeast of Bermuda. The official NHC prediction has Katia strengthening during this time, with forecasters expecting the storm to reach category 3 hurricane status tomorrow before less favorable conditions eventually weaken the system. Forecasts now indicate Katia is less likely to threaten land as the storm is expected to take a turn to the north later this week, remaining offshore midway between Bermuda and the east coast of the United States. The NHC forecast track then has the storm curving away to the northeast during the latter part of the week without affecting Bermuda or the United States. Most other forecast models also expect Katia to veer out to sea on a northeasterly track. However, the NHC stresses it is still too early to say with any certainty where Katia is headed and warned wind from the storm could still affect the United States east coast as it moves north. Large swells generated by Katia are also expected to affect the United States, Bermuda and Greater Antilles. The NHC said these swells are likely to cause life threatening surge and rip current conditions.
