The Oct. 5, 11 p.m. National Hurricane Center forecast tracking map shows Tropical Depression Karen located about 185 miles west-southwest of the mouth of the Mississippi river.
Tropical Storm Karen weakened to a depression Saturday night, reducing the treat of damage to several Gulf Coast states.
The National Hurricane Center reported at 11 p.m. that the tropical storm was no more. Maximum sustained winds were down to 35 mph. A tropical storm must have maximum sustained winds of at least 39 mph.
Karen remained stalled much of the evening. The depression’s last reported location was 120 miles south-southwest of Morgan City, La., and 185 miles west-southwest of the mouth of the Mississippi River.
No tropical storm warnings remain in effect. The NHC advises residents along the north-central Gulf Coast to stay tuned for the latest weather forecasts. Increased winds, potential storm surge and rainfall of 1 to 3 inches is possible, especially near or to the right of the center’s path.
The center of the depression should move near or over parts of extreme southeastern Louisiana on Sunday and move just south of the Gulf Coast from Alabama to the Florida Panhandle on Sunday and Sunday night.
NHC meteorologists said re-strengthening is not likely due to infiltration of drier air. Karen is expected to dissipate within 72 hours.
Karen is not expected to affect weather in Pinellas County or Tampa Bay. The National Weather Service canceled its notice of an increased risk of rip tides. However, boaters are still advised to keep an eye on the storm’s track, as winds and seas could increase to near advisory levels Sunday night and Monday.
Pinellas County Emergency Management cautioned residents to stay prepared for possible tropical weather in October, which is the third busiest month for hurricane development. More than 16 percent of all storms have formed in October.
“When cold fronts blow out of Canada, bringing cooler air to our neighbors up north, the winds they generate tend to pick gulf storms up and push them from west to east making Florida’s west coast particularly vulnerable,” Tom Iovino, public information specialist with county Communications, said in a press release.
The last time Pinellas County took a direct hit from a hurricane was Oct. 25, 1921. On Oct. 7, 1996, Tropical Storm Josephine caused flooding along the county’s beaches and swept a “tremendous amount of sand onto Gulf Boulevard,” Iovino said.
Hurricane Wilma, which make landfall on Oct. 24, 2005, broke several records, eventually becoming the most intense hurricane recorded in the Atlantic Basin.
Iovino said that since October storms form much closer to the county, the warning time could be considerably shorter than storms forming in August and September. Residents are urged to visit www.pinellascounty.org/emegency to verify evacuation levels and get information on disaster planning.
While it is still too soon to tell with any certainty, computer-generated tracking maps of potential paths for Invest 97L, should it develop, show it making landfall anywhere from the coast of Louisiana to the west coast of Florida. Residents are urged to keep tuned to the latest weather forecasts.
Renowned hurricane forecasters Phillip Klotzbach and William Gray, professors with the Department of Atmospheric Science at Colorado State University, released their latest forecast Sept. 27 for a period lasting through Oct. 10. The forecast is for below-average amounts of hurricane activity through the period.
“The most recent seasonal forecast called for an above-normal season,” the Colorado experts said. “Obviously, at this point, we realize that the seasonal forecast was a significant over-prediction, and we therefore do not expect to see the levels of activity this year that we earlier anticipated.”
But, it only takes one – that’s the anthem emergency management personnel and meteorologists sing ever hurricane season, which is June 1 to Nov. 30 for the Atlantic basin. Residents who live in areas vulnerable to hurricanes are urged to stay ready and be ready to put emergency plans into action if necessary.
The Atlantic basin includes the Atlantic Ocean, Caribbean Sea and Gulf of Mexico.
It was Sept. 11 before the first hurricane of the 2013 Atlantic hurricane season formed. Three days later, a second hurricane formed about 195 miles east of Tuxpan Mexico.
The first hurricane of the season, Humberto, had become a post-tropical cyclone as of Sept. 14. It became a tropical storm again on Sept. 16 and maintained its strength until Sept. 19 when it was downgraded into a tropical depression. Humberto remained over open water for its entire life cycle.
Ingrid formed as a Category 1 hurricane with maximum sustained winds of 75 mph on Sept. 14. It made landfall on the Mexican coast Sept. 16.
According to NHC records, 2013 is the first year since 2002 that no hurricane formed through the month of August. Records show that on average at least one hurricane forms in a season by Aug. 10.
The National Oceanic and Atmospheric Administration’s climate experts have predicted that as many as six to nine hurricanes could form during the 2013 Atlantic hurricane season. As of Oct. 3, 11 named storms have formed. NOAA’s forecast calls for 13 to 19.
Andrea was the season’s first tropical storm. It formed June 5 in the east-central Gulf of Mexico. Andrea had winds of about 65 mph when it made landfall in Dixie County about 10 miles south of Steinhatchee about 5:40 p.m. June 7. Andrea brought wind and rain to Pinellas County, causing minor damage to the beaches. Rain bands from the storm spawned a tornado that touched down in Gulfport the morning of June 6.
Tropical Storm Barry started as a tropical depression on Monday, June 17, as it approached the coast of Belize on the northeastern coast of Central America. It strengthened into a tropical storm June 19 in the southern Gulf of Mexico and made landfall along the coast of Mexico June 20.
The third tropical storm was short-lived. Chantal formed July 7 over the central tropical Atlantic Ocean and degenerated into a tropical wave July 10.
Dorian was the fourth tropical storm of 2013. It formed the morning of July 24 in the eastern tropical Atlantic Ocean. It was downgraded to a tropical depression July 27.
Erin brought the count to five. It started as a depression on Aug. 15 and strengthened into a tropical storm the same day. Erin was downgraded back to a depression on Aug. 16, strengthened into a storm again on Aug. 17 before wind speeds decreased and Erin’s status returned to a depression.
Tropical Storm Fernand began as tropical depression six on Aug. 25 in the southwest Gulf of Mexico and strengthened into a named storm that same day. It made landfall Aug. 26 along the coast of Mexico.
Gabrielle was another short-lived storm, forming Sept. 5 and dissipating the next day. However, the storm regenerated Sept. 10, taking aim at Bermuda. The storm was downgraded to a depression on Sept. 13.
The peak months of the Atlantic basin hurricane season are August through October, and about 55 percent of tropical storms and hurricanes form during the months of September and October. Pinellas County’s Emergency Management Department reminds residents that strong and destructive storms such as last year’s Hurricane Sandy, Wilma in 2005 and the 1921 Tampa Bay Hurricane all made landfall in October.
“Now is not the time to let our guard down,” said Tom Iovino, with Pinellas County Communications.
