Hurricane Cora was a tropical cyclone which affected the Lesser Antilles during August 1978. The first hurricane of the 1978 Atlantic hurricane season, Cora originated as a disturbance that exited the African coast on August 7, the storm moved at an unusually high forward speed for a cyclone in the Atlantic Ocean in August. The storm later reached hurricane strength and formed a well-defined eye that lasted only 12 hours before the eye rapidly lost organization for unknown reasons, though the post-season report on the storm mentions the possibility that its high speed caused the eye to dissipate. The storm moved west-southwestward, weakening before making landfall on the island of Grenada. The storm lost its circulation and became a tropical wave on August 12. The remnant crossed over Central America into the Pacific Ocean, where it reintensified, becoming Hurricane Kristy.

Cora was an unusual cyclone, maintaining an unusually low latitude for the Atlantic in August at high speeds, similar to the tracks of Tropical Storm Alma in 1974 and Tropical Storm Fran in 1990. The hurricane was also upgraded into a hurricane based solely on satellite photography, the second time this occurred. Although it passed through the Windward Islands and the Lesser Antilles, only minor effects were reported. Cora was also responsible for altering weather conditions allowing for a takeoff of the historical flight of the Double Eagle II hot air balloon. (Full article...)

Tropical cyclones and subtropical cyclones are named by various warning centers to simplify communication between forecasters and the general public regarding forecasts, watches and warnings. The names are intended to reduce confusion in the event of concurrent storms in the same basin. Once storms develop sustained wind speeds of more than 33 knots (61 km/h; 38 mph), names are generally assigned to them from predetermined lists, depending on the basin in which they originate. Some tropical depressions are named in the Western Pacific, while tropical cyclones must contain a significant amount of gale-force winds before they are named in the Southern Hemisphere.

Before it became standard practice to give personal (first) names to tropical cyclones, they were named after places, objects, or the saints' feast days on which they occurred. Credit for the first usage of personal names for weather systems is generally given to Queensland Government meteorologist Clement Wragge, who named systems between 1887 and 1907. When Wragge retired, the practice fell into disuse for several years until it was revived in the latter part of World War II for the Western Pacific. Formal naming schemes and lists have subsequently been used for major storms in the Eastern, Central, Western and Southern Pacific basins, and the Australian region, Atlantic Ocean and Indian Ocean.

The 1933 Atlantic hurricane season is the most active Atlantic hurricane season on record in terms of accumulated Cyclone Energy (ACE), with a total of 259. It also set a record for nameable tropical storms in a single season, 20, which stood until 2005, when there were 28 storms. The season ran for six months of 1933, with tropical cyclone development occurring as early as May and as late as November. A system was active for all but 13 days from June 28 to October 7.

Because technologies such as Earth observation satellites were not available until the 1960s, historical data on tropical cyclones from the early 20th century is often incomplete. Tropical cyclones that did not approach populated areas or shipping lanes, especially if they were relatively weak and of short duration, may have remained undetected. Compensating for the lack of comprehensive observation and the limited technological ability to monitor all tropical cyclone activity in the Atlantic Basin during this era, research meteorologist Christopher Landsea estimates that the 1933 season may have produced an additional 2–3 missed tropical cyclones. A 2013 reanalysis of the 1933 Atlantic Hurricane Database did indeed identify two new tropical storms; however, it was also determined that two existing cyclones did not reach tropical storm intensity and so were removed from the database. Additionally, researchers found two existing storms to be one continuous system. As a result, the season storm total dropped from 21 to 20. (Full article...)

August 11,

• 1856 - The 1856 Last Island hurricane made landfall in Louisiana as a Category 4 hurricane, obliterating Last Island (a.k.a. Isle Dernière). At least 200 people were killed.
• 1987 - Typhoon Betty (track pictured) reaches peak intensity with 1-minute sustained winds of 260 km/h (160 mph) with a pressure of 890 hPa while making landfall over northern Samar.

• August 12, 2004 - Typhoon Rananim (pictured) reached its peak intensity to the east of Taiwan with 170 km/h (105 mph) winds. Ranamin later made landfall in Zhejiang, China killing 115 people and causing over $4 billion in damage.

August 13,

• 2004 - Hurricane Charley (pictured) made landfall as a Category 4 hurricane near Punta Gorda, Florida. Charley caused over $16 billion in damage.
• 2009 - Tropical Storm Maka enters the Pacific typhoon basin from the Central Pacific.

• …that the Joint Typhoon Warning Center considers that Typhoon Vera (pictured) of 1986 is actually two distinct systems, formed from two separated low-level circulations?
• …that Hurricane Agatha (pictured) was the strongest Pacific hurricane to make landfall in Mexico in May since records began in 1949?
• …that Cyclone Raquel (track pictured) travelled between the Australian and South Pacific basins between the 2014–15 and 2015–16 seasons, spanning both seasons in both basins?
• …that Cyclone Amphan (pictured) in 2020 was the first storm to be classified as a Super Cyclonic Storm in the Bay of Bengal since 1999?
