The NHC will name assign the name Ana to Invest 90L off the coast of South Carolina at 10 p.m. CDT.

The maximum winds measured by the stepped frequency microwave radiometer on the Air Force plane was 45 mph. The central pressure was 104 mb.

The storm is still a hybrid storm, with subtropical and tropical characteristics. The center is slightly warmer than the surrounding part of the storm. But winds are strongest well away from the center. Some of the strongest winds are very close to the South Carolina coast.

Ana Is That You?

There is still consistent evidence that a subtropical storm could form northwest of the Bahamas by midweek. This subtropical storm could affect the Carolinas and Georgia coastline, but top winds should be less than 50 mph. Gusty winds and rough surf will be the main impact. Sill, it serves as a reminder that the Atlantic Hurricane Season is not far away, beginning June 1.

BILL ON DECK: I get a storm named for me this year! The name Bill has been used for three tropical cyclones in the Atlantic. 2009’s Bill was a Cat 4 Hurricane that passed Bermuda and grazed Nova Scotia. 1997’s Bill threatened Bermuda as well. Seems I have a thing for Bermuda. And TS Bill in 2003 made landfall west of New Orleans.

Here is the list of names for 2015 in the Atlantic:

Ana

Hanna Forms

Hanna avn_lalo-animated

The remnant low from Tropical Depression #9, which formed over the southwestern Caribbean last week and moved across the Yucatan into the northwestern Caribbean has developed into Tropical Storm Hanna this morning.

Hanna 130316W5_NL_sm

It is very near the coast of Nicaragua and will move into that country today. Tropical Storm Warnings are in effect along the coasts of Nicaragua and Honduras.

Top winds are 40 mph. Heavy rains of 10-15 inches will be the main problem with life threatening landslides likely.

Hello Gonzo! Well, Actually Gonzalo…

| 1:07 pm October 12, 2014

We have experienced a little burst of activity in the tropical Atlantic as a cycle called the Madden Julian Oscillation (MJO) is bringing favorable conditions to much of the basin.

Gonzalo avn-animated

Tropical Storm Fay scored a direct hit on the island of Bermuda overnight. Winds officially gusted to 82 mph as the 70 mph tropical storm passed just east of the island after midnight last night. Winds dropped to near calm as the center passed and the barometer was measured at 986 mb. It will continue to the east northeast over open ocean over the next few days.

Now comes Gonzalo…

Based on Air Force Reconnaissance reports from the disturbance east of the northern Leewards, the National Hurricane Center is now issuing advisories on newly formed Tropical Storm Gonzalo. Gonzalo will produce tropical storm conditions across the northern Leewards, Virgin Islands and perhaps Puerto Rico. The system will recurve to the north.
