Tropical Storm Norbert, currently off the west coast of Mexico, has officially been upgraded to a hurricane as of Wednesday.
Currently, the maximum sustained winds are being reported at approximately 75 miles per hour with hurricane force winds extending outward up to 25 miles from the center of the storm. Hurricane Arthur reached Category 2 strength on July 3 before cutting across North Carolina's Outer Banks.
That's likely because steering currents over the Atlantic tended to curve the few storms that formed in a northern direction, away from the Caribbean Sea and into the Atlantic, said Gerry Bell, lead hurricane forecaster for NOAA's Climate Prediction Center, in a telephone interview Monday. Hurricane Arthur's rainfall as it crosses the North Carolina coast, captured by NASA's Global Precipitation Measurement Core Observatory. Bell credited a combination of atmospheric conditions for making it difficult for hurricanes to form in 2014, including very strong vertical wind shear in the atmosphere above areas where storms usually formed, stronger sinking motion for air in the upper atmosphere in those same areas, and drier air across the tropical Atlantic. What seemed not to be a direct factor was El Nino, despite predictions that the warm-water conditions in the eastern and central Pacific would develop at the height of the hurricane season and increase storm-killing shear in the Atlantic.
In the interview, Bell said it's way too soon to begin predicting what will happen during the 2015 hurricane season, which will last from June 1 to Nov.

It's also unclear whether a longer-term climate cycle believed responsible for more active hurricane seasons since 1995 remains in effect. Bell said even more important, though, is for the public not to become complacent because of a lull in hurricane activity.

Forecasters credited NOAA's upgraded hurricane climate model, the Hurricane Weather Research and Forecasting, or HWRF, model for accurately forecasting Arthur's landfall on the Outer Banks of North Carolina and for other accurate forecasts during the season. The National Hurricane Center also rolled out two new products during the 2014 season, an experimental five-day graphical tropical weather outlook forecast for both the Atlantic and North Pacific basins, and an experimental potential storm surge flooding map for areas along the Gulf and Atlantic coasts in advance of landfalling storms. Norbert is the ninth named storm in a busy hurricane season in the Eastern Pacific, reports say. PST, Hurricane Norbert was located approximately 215 miles south of the southern tip of Baja California and is moving in a west-northwesterly direction at approximately eight miles per hour.


The hurricane is expected to change course from its current west-northwest trajectory and turn to the northwest, continuing on that track over the next day or two. If the depression does form into a more organized system, Tropical Depression Bertha would become the second named storm of the 2014 hurricane season. The wind shear over the Atlantic has reportedly been rather strong for most of the 2014 hurricane season thus far.
30) after producing only eight named storms, including six hurricanes, of which only two were major, National Weather Service forecasters said.
Nevertheless, we know that's not always going to be the case," said Louis Uccellini,, director of NOAA's National Weather Service, in a news release marking the end of the season.
