How to use this page:
The title of each of the figures below is linked to the page where the information originates.
Since I write and post early in the day and generally do not update the page until the next morning; by clicking on the link, it allows you, the viewer, to get the latest information.
This is not only convenient but allows you to track weather events such as cold fronts and hurricanes from a single web page.
In addition, in the right column is a very useful widget. It is a trip planner...yesteryear's weather at a glance.This widget lets you check historic weather for your trip dates.

2014 Hurricane Outlook and Forecasts
The hurricane season in this hemisphere starts on June 01 and ends on November 30.
During that time frame, for your convenience, you will find a section below titled, "Tropical Weather Outlook".
It will contain the daily tropical storm outlook, forecast and storm track(s).

NOAA predicts near-normal or below-normal 2014 Atlantic hurricane season.
El Niño is expected to develop and suppress the number and intensity of tropical cyclones.
This year, the Saharan Air Layer (SAL) has been decreasing in size and density since May 21, 2014. This is important because it has been postulated, that the SAL, a cool, dry, layer of air which contains particles, may inhibit the formation of tropical storms and hurricanes. In addition, as it decreases in size and density, the probability of tropical storm formation may increase.

The outlook calls for a 50 percent chance of a below-normal season, a 40 percent chance of a near-normal season, and only a 10 percent chance of an above-normal season.  For the six-month hurricane season, which begins June 1, NOAA predicts a 70 percent likelihood of 8 to 13 named storms (winds of 39 mph or higher), of which 3 to 6 could become hurricanes (winds of 74 mph or higher), including 1 to 2 major hurricanes (Category 3, 4 or 5; winds of 111 mph or higher).
These numbers are near or below the seasonal averages of 12 named storms, six hurricanes and three major hurricanes, based on the average from 1981 to 2010. The Atlantic hurricane region includes the North Atlantic Ocean, Caribbean Sea and Gulf of Mexico.

Friday,  September 18, 2014
Today, skies will be mostly sunny. Winds will be easterly in direction today at 5 mph to 15 mph. Seas will be moderate at 1 to 3 feet. Expect  these wind and sea conditions to prevail through most of next week. There is a very slight chance of scattered rain showers and isolated thunderstorms, especially during the early morning, late night hours.
The air temperatures will range from the mid to high 70s (ºF) to the mid to high 80s (ºF) or 24ºC to 26ºC.
Ocean water temperatures are 82°F to 84°F or 24ºC to 25ºC. Visibility is 20 to 80 ft.

The Tropical Weather Outlook
The Tropical Weather Outlook
1. The National Hurricane Center is issuing advisories on Tropical Storm Edouard, located several hundred miles west-northwest of the western Azores.
2. Disorganized showers and thunderstorms continue in association with a broad area of low pressure located between the west coast of Africa and the Cape Verde Islands. Some development of this system is possible over the next few days before upper-level winds become less conducive. This low is expected to move slowly west- northwestward or northwestward and could bring heavy rainfall to portions of the Cape Verde Islands this weekend.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...30 percent.
3. A tropical wave over the E Caribbean will move across the central Caribbean through Friday night...then will weaken as it moves across the W Caribbean through early next week. Another tropical wave will pass 55W by early Saturday...enter the E Caribbean Sunday...and move across the central Caribbean through early next week. Otherwise...moderate to locally fresh trades will prevail across the area through the period.

African tropical wave 95L off the coast of Africa
A tropical wave (Invest 95L) that emerged from the coast of Africa on Wednesday night is being given lukewarm support for development by two of our three reliable tropical cyclone genesis models. Satellite loops show 95L has a moderate degree of spin, but its heavy thunderstorm activity is sparse and disorganized. The wave is under light wind shear and over warm waters of 28°C (82°F), conditions that favor development. In their 8 am EDT Friday Tropical Weather Outlook, NHC gave the wave 2-day and 5-day odds of development of 20% and 30%, respectively. This wave is expected to move northwest near or over the Cape Verdes Islands by Sunday. Once it is northwest of the islands early next week, 95L will encounter drier air, making further development difficult. If 95L does develop, I doubt it would affect any land areas besides the Cape Verde Islands.
