With parts of Central America still reeling from flooding and landslides caused by Hurricane Eta, Tropical Storm Iota is now forecast to hit the region at or near major hurricane strength early next week, bringing with it up to 30 inches of rain.
Tropical Storm Iota has winds of 50 mph and is about 375 miles south of Kingston, Jamaica, on Saturday. The storm is moving west-southwest at 5 mph.
Unfortunately, Iota is expected to strengthen over the next 48 hours and should reach hurricane strength later on Sunday. By Monday and Tuesday, Iota will likely be a Category 2 hurricane with 110 mph winds as it approaches Nicaragua and Honduras' coast.
Hurricane watches are now in effect for portions of the Nicaragua and Honduras coastlines.
The current track also brings Iota very close to where Eta made landfall in Central America earlier this month. Eta made landfall as a Category 4 in Nicaragua, with winds of 140 mph. Eta is estimated to have brought over 35 inches of rain to the region, causing catastrophic flash flooding and causalities.
Computer guidance indicates that Iota could bring another 30 inches to parts of Central America. This could aggravate recovery efforts underway. More mudslides, landslides and flash flooding will be likely. This could potentially be a major disaster if the forecast holds.
Iota is the 30th named storm of the 2020 Atlantic hurricane season, which is a record for most named storms in a single Atlantic hurricane season. That record was just broken with the formation of Theta earlier this week.
2 fronts affecting US weather
Meanwhile in the U.S., there are two storm systems impacting parts of the country this weekend.
A strong frontal system forming in the central U.S. will bring rain and snow showers to parts of the upper Midwest, while strong to severe thunderstorms are heading toward parts of the southern Plains. Gusty winds will be particularly likely in Denver and Oklahoma City Saturday.
When the colder air rushes in behind the cold front on Sunday, strong gusty winds will be possible from Missouri all the way to New York State, including Chicago, Detroit and Buffalo. Gusty winds, locally over 45 mph, could bring down power lines and down trees.
When the cold front comes to the East Coast, there could be a brief opportunity for strong thunderstorms, torrential and gusty downpours near the major northeast cities, and then another round of strong winds immediately behind the front late Sunday night.
