The 2020 hurricane season continues its relentless onslaught as Tropical Storm Eta, the 28th named storm of the season, lashes Central America with torrential rains and whipping winds. Typically Central America is a graveyard for hurricanes — but not Eta. Increasingly, forecasters are concerned Eta will reemerge over the warm Caribbean waters and then head toward Florida this weekend.
Right now, Eta is gradually weakening over land, but it's expected to head into the Caribbean Friday and move northeastward. The models show the system reorganizing, with some modest restrengthening this weekend over the Caribbean and the Florida Straits, north of Cuba. On this path at least two more landfalls seem likely: Cuba on Sunday and possibly South Florida on Monday.
If Eta makes landfall along the U.S. coastline, it would break the record for the most named storms to make a U.S. landfall in a season, at 12. If it regains hurricane strength, that would break the record for most landfalling U.S. hurricanes.
As of Wednesday afternoon, Tropical Storm Eta is located inland near the Honduras-Nicaragua border, continuing to move west deeper into Central America. The system is forecast to weaken further to a tropical depression but continue to dump torrential rains and cause flash flooding.
Later this week, Eta will begin to feel the influence of upper-level steering to its north causing the storm to make a hard right turn, pushing it back over the hot northern Caribbean waters. While some intensification is likely, it will be limited, at least initially, because Eta will have to contend with some dry air, upper-level wind shear, interaction with the landmass of Cuba, and limited time.
By Saturday the system will cross over Cuba, likely as a tropical storm, and then head towards South Florida. It is still uncertain how strong Eta will be and the degree to which the storm will impact South Florida. Most likely Eta will either be a strong tropical storm or even a low-end hurricane. Some models show a direct hit, while others show a glancing blow over the Florida Keys.
Regardless of exact track, Eta will bring a stretch of very wet weather across South Florida from Friday through early next week. Depending on the track, over a foot of rain seems likely in some spots.
After the storm passes South Florida, most models then show it snaking back westward into the Gulf of Mexico early next week. Gulf waters are still warm enough for Eta to once again regain strength. Although it is too early to know if and where another landfall could take place, some guidance suggests yet another Gulf Coast landfall is possible by the middle of next week.
