- Invest 97-L was upgraded to Tropical Storm Earl on August 2, 2016.
This is a developing weather story. Please suction stop hera for the latest updates. A tropical mental disorder, Invest 97-L, was upgraded to Tropical Storm Earl Tuesday, August 2, after a Hurricane hunter reconnaissance mission found a surface low-pressure center associated with the convection south of Jamaica.
(MORE: What is an Invest?) This system is headed toward parts of Mexico and Central America with the threat of heavy rain, high surf, and gusty, possibly damaging winds. technically, the Atlantic hurricane season runs from June 1 through Nov. 30. much of the tropical activeness occurs between the second base week of August and the second week of October. In late July and early August, we begin to keep an eye on the eastern Atlantic as it begins to show signs of life. (MORE: When the Atlantic Hurricane Season Ramps Up)
August and September: More Favorable For Development
tropical waves that emerge off the African seashore frequently develop around or after passing the Cape Verde Islands. ( MORE: Why Tropical Waves Are Important ) Meteorologists make frequent references to the “ Cape Verde ” temper, which is basically a season within the overall hurricane season. Most Cape Verde storms develop from mid-august until late September . Expanding high pressure ridge creates a more friendly environment for tropical systems to develop and move westward in the Alantic ad
There are so many “ mouse traps ” ( unfavorable conditions ) in the Atlantic that identical few of these Cape Verde tropical storms and hurricanes ever make it all the way to the United States. But there have been some celebrated Cape Verde storms that made it to the East Coast of the U.S., such as the 1938 Hurricane, Hurricane Hugo in 1989 and Hurricane Andrew in 1992. Development of tropical waves into tropical storms or hurricanes is determined by several environmental factors that can range from slightly golden to extremely favorable, including :
- Ocean temperatures
- The orientation of ridges (high pressure) and troughs (low pressure) aloft
- A moist environment
In general, the ocean temperature needs to be around 80 degrees for tropical cyclones to develop. Off the coast of Africa, that does n’t normally occur until recently July. tropical systems like to have winds that are roughly the lapp focal ratio and commission through a depth of the atmosphere for maximum development. Wind shear – changing winds with altitude – tends to break up tropical systems that are trying to develop, displacing convection away from a center of circulation. This often occurs when a trough of humble pressure aloft is to the west of a tropical weather system, such that west to southwest winds aloft combine with the typical tropical east-northeast trade winds to produce scent shear. In August and September, a hard-hitting ridge aloft, known as the Bermuda-Azores high, much expands and creates a more golden environment for development. Atlantic systems are often steered toward the western Atlantic, Caribbean Sea and sometimes all the way to the U.S. Since the area from Africa to the easterly Atlantic looks quite active already and we now have a tropical system of matter to, it ‘ll be concern to see what the rest of the hurricane season will have in storehouse.

1/93 Hurricane Iota made landfall at Category 4 saturation on Nov. 16, 2020, near Haulover, Nicaragua. This was just 15 miles south and 13 days after the landfall of Hurricane Eta. Before landfall, Iota became entirely the second Atlantic Basin Category 5 November hurricane on record. Massive rain deluge once again swamp Nicaragua, Honduras and Guatemala .
