The 1977 Atlantic hurricane season officially began on June 1, 1977, and it ended on November 30, 1977; these are dates that conventionally delimit the timeframe for tropical cyclone formation. It was rather inactive due to the presence of a moderate El Niño. While 16 total depressions and 14 tropical storms formed, both above average, only three hurricanes and no majors formed, the lowest numbers since 1972.

The lone notable storm of the season was Hurricane Jodie, which produced torrential rainfall over much of Louisiana and Mississippi, prompting a state of emergency. It was the costliest hurricane in U.S. history for its time.

The real season witnessed 16 depressions, 6 storms, 5 hurricanes, and 1 major hurricane.

Peak intensity 35 mph (55 km/h) (1-min)  999 mbar (hPa)

Duration September 10 – September 17
Peak intensity 85 mph (140 km/h) (1-min)  984 mbar (hPa)

Tropical storm (SSHWS)
DollyAug919682054UTCESSA5.gif
Duration September 25 – September 30
Peak intensity 65 mph (100 km/h) (1-min)  992 mbar (hPa)

Grace made landfall over The Bahamas and Florida as a strong tropical storm before attacking Louisiana under its brief second spell. Strong gusts of hurricane intensity and a storm surge of five to seven feet destroyed many palm trees and mobile homes, as well as threatening the levees surrounding New Orleans. All in all, eight fatalities and $45 million (1977 USD) in losses was reported.


Tropical Storm Hannah

Tropical storm (SSHWS)
Janice 71.jpg
Duration October 3 – October 8
Peak intensity 60 mph (95 km/h) (1-min)  993 mbar (hPa)

Hannah did not affect land.


Hurricane Ida

Category 1 hurricane (SSHWS)
Hurricane Debra 1959.JPG
Duration October 12 – October 18
Peak intensity 85 mph (140 km/h) (1-min)  978 mbar (hPa)

Ida made landfall in Louisiana as a weak hurricane. Widespread power outages affected thousands of customers and rainfall nearing 15 inches flooded regions of additional Greater New Orleans already badly saturated from earlier storms. Primarily due to roof and structural damage, the hurricane caused 12 fatalities and $108 million (1977 USD) in losses.


Hurricane Jodie

Category 1 hurricane (SSHWS)
Hurricane Agnes.jpg
Duration October 16 – October 27
Peak intensity 90 mph (150 km/h) (1-min)  972 mbar (hPa)

Jodie was a very erratically moving storm which made multiple landfalls over Louisiana, partially influenced by a Fujiwhara interaction with Ida's remnants. Rainfall nearing 40 inches, over 60 tornadoes, and gusts of major hurricane intensity snapped dozens of trees, flooded marshes and the Mississippi River Delta, and destroyed thousands of structures across New Orleans. A storm surge of nearly 15 feet crashed through the levees protecting New Orleans from Lake Pontchartrain; in some places, the surge exceeded levels set by Betsy and Katrina a couple of decades later. Roughly 60% of the city's infrastructure was destroyed, 50,000 people were left homeless, and hundreds of businesses went out of operation. The damage was so severe, President Jimmy Carter declared southern Louisiana a disaster zone. Overall, damages from Jodie reached $4.7 billion (1977 USD) and 643 fatalities were reported. This made the hurricane the costliest in American history until Hugo twelve years later.


Tropical Storm Kristina

Tropical storm (SSHWS)
CandyJune2119682112UTCESSA5.gif
Duration November 1 – November 5
Peak intensity 60 mph (95 km/h) (1-min)  994 mbar (hPa)

Kristina made landfall over Louisiana in roughly the same spot Jodie had been looping around only a week earlier. Rainfall of three to five inches and gusts of hurricane intensity destroyed 15% of the refugee camps set up in New Orleans and threatened to overtop the Lake Pontchartrain levees for a second time. Eleven fatalities and $65 million (1977 USD) in losses were reported.


Tropical Storm Lois

Tropical storm (SSHWS)
DorothyJul231966ESSA1.gif
