Major Hurricane Ophelia Just Southeast of the Azores (credit: NWS National Hurricane Center)
DISCUSSION: As of earlier this evening, Hurricane Ophelia continues to impress the meteorological world as the storm has now reached the status of being a major hurricane as of earlier this evening. This is without a doubt one of the more impressive hurricanes in the eastern Atlantic Ocean in recent memory. The primary reason for this particular tropical cyclone being so impressive is the fact that Ophelia is positioned at a particular high latitude and relatively eastern longitude with respect to the expanse of the entire tropical Atlantic Ocean basin. Hence, tropical cyclones do not often form and/or exist at this particular part of the Atlantic Ocean basin at any time during the course of a tropical cyclone season. That fact is also reflected by the upper-most graphic attached above which visually illustrates the actual rarity of a tropical storm (let alone a major hurricane) developing within that part of the eastern Atlantic Ocean (courtesy of Meteorologist Sam Lillo). Thus, as this continues to take aim at Ireland as well as the central/northern British Isles, people in these and other adjacent countries should remain vigilant as this hurricane continues to move further north with time.

Hurricane Nate Impacting Coastal Alabama and Mississippi Tonight (credit: Radarscope)
DISCUSSION: As of earlier tonight, Category 1 Hurricane Nate made its first landfall at the mouth of Mississippi River and then shortly after that time Hurricane Nate made a second landfall in the vicinity of Gulfport, Mississippi. Despite the fact that this tropical cyclone only made landfall as a Category 1 hurricane, there have already been multiple reports of 5 foot + storm surge impacting many areas across coastal Alabama and Mississippi. Thus, Hurricane Nate did not get to be comparably strong hurricane with respect to the tropical cyclones which occurred during the month of September this year. However, Nate has still created tremendous flooding problems due to the combination of heavy rainfall and a prolific storm surge. Therefore, hopefully people are taking the impacts and the soon-to-be aftermath of Hurricane Nate seriously as the post-storm impacts will have the potential to be just as (if not more) dangerous than the landfall itself of Hurricane Nate. Be sure to stay tuned for updates both here and on Twitter for the latest from the Global Weather and Climate Center team on impacts from Hurricane Nate.

Nate Targeting Louisiana-Northwest Florida Coast (H. Michael Mogil, CCM, CBM, NWA-DS*)
Hurricane Nate is nearing peak intensity (strong Category 1 hurricane with sustained winds of 90 miles per hour) as it races toward landfall on the Mississippi-Alabama coast tonight (Fig. 1). However, with the strongest winds and the greatest push of water toward the coast on its eastern flank, places from extreme eastern Louisiana to northwest Florida stand to take the greatest beating…To read the full story, click here - http://www.weatherworks.com/lifelong-learning-blog/?p=1417

DISCUSSION: We are past the climatological peak of the Atlantic hurricane season, and it appears that North America and the Caribbean will get a much needed break from any landfalling tropical cyclones over at least the next week or two. However, the hurricane season is not over. During the peak of the season, storms have a tendency to develop from easterly waves moving off the coast of Africa. However, this time of year easterly waves over the east Atlantic are weakening. Thus, storms have a tendency to spin up in the Caribbean Sea south of Cuba as indicated in the figure above and move northward. Of the 14 hurricanes that have made landfall in the U.S. in October since 1950, 8 of them have made landfall in Florida, many of them in south Florida. So, the key message here is that all people living in hurricane-prone regions need to continue to be vigilant and prepared. This is especially true of Florida, which is most at risk of an October landfall from a climatological perspective.
