tropical storm ana is over the Atlantic & here are the latest news about its impact.

tropical depression could develop into Tropical Storm Ana as early as today, which would be the first named Atlantic storm of 2009.
Forecasters say Tropical Storm Ana has formed over the Atlantic and could strengthen as it heads toward the Leeward Islands.The Cape Verde season is well under way as a series of waves have been spinning off the African coast.

Historic data just to compare & take necessary precautions.

Tropical Storm Ana Forms Over The Atlantic
MIAMI -- Tropical Storm Ana has formed over the Atlantic and could strengthen as it heads toward the Leeward Islands, forecasters said Saturday.

The National Hurricane Center in Miami said Ana could trigger a tropical storm watch for parts of the Leeward Islands later Saturday. It could be approaching the islands by Monday. It was 1,075 miles west of the islands early Saturday.

Ana, the first named storm of the Atlantic season, could slowly strengthen in the next couple of days as it moves to the west at 16 mph. Maximum sustained winds are near 40 mph.

Meanwhile, Hurricane Guillermo was swirling in the Pacific as a Category 3 storm. Winds were near 115 mph as the hurricane moved to the west-northwest at 16 mph. It was about 1,450 miles west of the southern tip of Mexico's Baja California peninsula early Saturday morning.

However, Guillermo was expected to weaken Saturday and become even less powerful Sunday as it moves over cooler waters.


Tropical Storm Ana forms in Atlantic, aims at Florida
Remember that tropical depression that died a few days ago?

Now it’s Tropical Storm Ana. And, of course, it’s aiming toward South Florida.

I told you, the tropics are full of surprises.

At 5 a.m. today, Ana was 1,010 miles east of the Leeward Islands with sustained winds of 40 mph. It was moving west at 16 mph.

If the current forecast holds, Ana would approach this region on Wednesday. Potentially, it could be a hurricane or a strong tropical storm with 70 mph winds.

The forecast track hints at a curve to the north before reaching this area. However, at this point nothing is certain.

The track likely will shift over the next few days and, bottom line, we need to watch it closely.

As for the strong wave in the eastern Atlantic, expect it to grow into Tropical Depression 3 today and then, likely, Tropical Storm Bill.

Models continue to point this system toward the Lesser Antilles and possibly the U.S. coastline.


Tropical Storm Ana
Our first tropical storm of the season has developed in the Atlantic. The Cape Verde season is well under way as a series of waves have been spinning off the African coast. Ana will continue on it’s westerly course for the next few days with a gradual strengthening. Another larger wave behind Ana is likely going to become a depression, and eventually turn into Tropical Storm Bill. On a quiet weather weekend, at least there is some tropical forecasting to monitor! The full details of Ana by the National Hurricane center inside!

Interests In The Leeward Islands Should Monitor The Progress Of Tropical Storm Ana. A Tropical Storm Watch May Be Required For Portions Of The Leeward Islands Later Today.

At 500 Am Ast… 0900 Utc… The Center Of Tropical Storm Ana Was Located Near Latitude 14.6 North… Longitude 46.8 West Or About 1010 Miles… 1630 Km… East Of The Leeward Islands.

Ana Is Moving Toward The West Near 16 Mph… 26 Km/Hr… And This General Motion Is Expected To Continue For The Next Couple Of Days With An Increase In Forward Speed. On This Forecast Track Ana Could Be Approaching The Leeward Islands On Monday.

Maximum Sustained Winds Are Near 40 Mph… 65 Km/Hr… With Higher Gusts. Slow Strengthening Is Forecast For Next 48 Hours.

Tropical Storm Force Winds Extend Outward Up To 70 Miles… 110 Km From The Center.

The Estimated Minimum Central Pressure Based On Data From Noaa Buoy 41041 Is 1005 Mb… 29.68 Inches.

Summary Of 500 Am Ast Information… Location… 14.6n 46.8w Maximum Sustained Winds… 40 Mph Present Movement… West Or 270 Degrees At 16 Mph Minimum Central Pressure… 1005 Mb

The Next Advisory Will Be Issued By The National Hurricane Center At 1100 Am Ast.

Forecast Discussion:
Satellite Images Indicate That The Tropical Depression Has Continued To Become Better Organized And Is Now Upgraded To Tropical Storm Ana. The Storm Is Displaying Improved Banding In The Western Semicircle Along With A Ball Of Convection Near The Center. Noaa Buoy 41041 Reported A Minimum Pressure Of About 1005 Mb As The Depression Passed Very Near The Buoy. The Initial Intensity Is Raised To 35 Kt For This Advisory In Agreement With Dvorak Intensity Estimates From Sab And Tafb.

The Initial Motion Estimate Is 270/14. The Global Models Are In Agreement That A Deep-Layer Ridge Will Strengthen North Of The Tropical Cyclone Over The Next Day Or So. This Pattern Favors The Track Of Ana Gradually Bending From A West To A West-Northwest Direction With An Increase In Forward Speed. The Only Significant Outliers To This Track Are The Gfdl And Gfs…Which Both Weaken The System Rather Quickly…Leading To A More Westward Track Of The Cyclone. In A Few Days…Some Of The Models…Such As The Gfs… Show A Weakness In The Ridge Over The Western Atlantic That Could Allow The Cyclone To Gain A Little More Latitude. This Weakness Appears To Be Caused By The Mid- To Upper-Level Low Currently Near 25n 65w. However…The Majority Of The Guidance Shows The Mid- To Upper-Level Low Moving West-Southwestward With Minimal Influence On The Strength Of The Ridge. Generally…The Models That Hold Onto Ana Are In Good Agreement Throughout The Forecast Period. The Nhc Track Forecast Is Shifted Toward The Southwest For This Advisory… But Not As Far As The Model Consensus.

The 0000 Utc Global Models Generally Forecast A More Conducive Environment For Strengthening Than Previous Cycles…Showing A Weaker Mid-Oceanic Trough Affecting The System. In Particular…The Ukmet And Nogaps Build Upper-Ridging Near The Cyclone With Light Shear Through The Period. However…The Ecmwf Shows Some Westerly Shear Developing In About A Day…But Even That Model Has Lighter Shear Conditions In A Few Days. The Intensity Guidance Runs The Full Spectrum This Morning…With The Gfdl Dissipating The System…While The Hwrf Shows A Category Two Hurricane By The End Of The Forecast Period. Given The Uncertainty In The Upper-Level Environment Later In The Forecast Period…The Official Intensity Forecast Is Increased Conservatively…In Best Agreement With The Ships Model But Below The Intensity Consensus.
