Tropical Storm Edward made landfall near Johnson Bayou, Louisiana at around 2:20 pm, with maximum sustained winds of 60 mph and a central pressure of 996mb. The Bayou is on a barrier island and is about 28 miles southeast of Port Arthur, Texas. When I lived in Texas, I was there many times to go through the Bird and Butterfly Sanctuary. The bayou is very beautiful. Edward will weaken quickly, bringing heavy rain and flood concerns.
So far, the season has seen 5 named storms, 0 hurricanes, and 0 major hurricanes.
Tropical Storm Arthur made a landfall near Galveston, Texas
and brought significant rain to parts of the Gulf coast and Southeastern United
States in mid-June. Tropical Storm Bertha in July had two Gulf Coast landfalls, the
first was St. Bernard Parish, Louisiana and the second was near the Louisiana
and Texas border. Tropical Storm Cristobal formed in the middle of
this month and because of hostile conditions only lasted 24 hours. Dolly was the
season's fourth named storm, Dolly remained a tropical storm for only a few
hours, before wind shear, dust and dry air tore her apart.
The lack of a lot of Atlantic tropical activity is not
surprising if you have followed my blog post over the last few months, you already knew it would be. Stronger
El Ninos typically results in hostile wind shear (changes in wind speed and
direction), in the Atlantic Basin. This increase in wind shear can shred storms
before they even develop, or as we’ve seen this season weaken storms that do
form. Saharan dust has been another factor suppressing activity. Saharan Air
Layer is a mass of very dry, dusty air that forms over the Sahara Desert during
the late spring, summer and early fall, resulting in unfavorable conditions for
tropical development.
The number of named storms isn’t the only metric to look at.
Accumulated cyclone energy (ACE) is another way to measure how active the
season has been. ACE, is used to not just count storms, but also how long each
storm lasts and how strong each becomes. Adding the ACE of each storm gives us
one measure of how active a season is.
In terms of ACE, it's been the slowest-starting Atlantic
hurricane season since 1998, as of this writing Atlantic ACE stands at 4.1. The
average ACE unit measurement in the North Atlantic for September 1st is about
36 to 40 units. So, we can see the ACE is well below average.
Hurricane Bob was the first hurricane of the 1991 Atlantic
Hurricane Season. Bob reached peak winds of 115mph to the east of Virginia,
before weakening and slamming into Block Island, Rhode Island. Then about 40
minutes later, he made a 2nd landfall at Newport Rhode Island, with winds
of 100mph, making it a Category 2 hurricane. Bob still ranks as the most
powerful landfalling hurricane from the last five strong or very strong "super" El Nino
seasons of 1972, 1982, 1991, 1997, and 2015. No hurricane has made landfall in
New England since Bob.
Both of these show a season that seems subdued can become dangerous. It only takes one storm taking the right track, or wrong track, depending on how you look at it, to make it an active and memorable season.
