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.

Thursday,  September 25, 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 tomorrow with the passage of another tropical wave.
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. An elongated low pressure area designated Invest 96L, located about 1100 miles east of the Windward Islands is producing disorganized showers and thunderstorms. Environmental conditions are not conducive for significant development and tropical cyclone formation is unlikely.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.
2. A tropical wave in the central Caribbean will move across the W Caribbean through Friday night. Another tropical wave along 59W will move across the Lesser Antilles and far E Caribbean tonight and into Friday...and across the rest of the E Caribbean during Friday...the central Caribbean Friday night and Saturday...and W Caribbean Saturday night through Sunday night. Except for moderate trades in the SE portion Sunday afternoon through Monday... mostly gentle easterly trades will prevail across the area through the forecast period.

96L Little Threat

By: Dr. Jeff Masters , 1:04 PM GMT on September 25, 2014
In the Atlantic, a small area of low pressure (Invest 96L) formed Wednesday evening in the middle Atlantic Ocean near 15°N 45°W, about halfway between the Lesser Antilles Islands and the Cape Verde Islands. Satellite loops show that 96L has a pronounced low-level spin, but only a small amount of heavy thunderstorms. Water vapor satellite loops show 96L is surrounded on all sides by large amounts of dry air. With wind shear expected to stay moderate for the next five days, this dry air is likely to keep 96L from developing. None of the reliable tropical cyclone genesis models predict that 96L will develop, and In their 8 am EDT Thursday Tropical Weather Outlook, NHC gave 96L 2-day and 5-day odds of development of 10%. The storm should move slowly northwest during the remainder of the week.
