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.

Wednesday,  September 24, 2014
Today, skies will be partly sunny. Winds will be light and mostly easterly in direction at 5 mph to 10 mph or less. Seas will be calm at 1 to 3 feet. This morning's satellite images show the center of the tropical wave is to the west of us and will continue to slowly pass over us today and tonight. Expect  cloudiness and scattered, intermittent rain to decrease with its passage.
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
1. For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Tropical cyclone formation is not expected during the next 5 days.
2. A tropical wave extending from Haiti to NE Colombia will move across the rest of the central Caribbean through tonight ...then across the W Caribbean Thursday through Friday night. A second tropical wave currently along 50W/51W will move through the tropical N Atlantic waters tonight and Thursday...the E Caribbean Thursday night and Friday...the central Caribbean Friday night and Saturday...then the W Caribbean Saturday night through Sunday night. Except for moderate trades in the SE portion Saturday through Sunday night...mostly gentle easterly trades will prevail across the basin through the upcoming weekend.

Quiet in the tropics
The tropics are unusually quiet for September, with no tropical cyclones active. In the Atlantic, none of our reliable models for predicting tropical cyclone genesis shows anything developing over the next five days. A tropical wave coming off the coast of Africa on Friday may be something to watch for development late next week in the Caribbean, the GFS model is predicting, but it is too early to assign a probability of such an event occurring. Dry air will interfere with development of this wave as it crosses between the coast of Africa and the Lesser Antilles Islands.
