Tropical Depression 21 dissipates over Central America but still poses threats of flooding, mudslides
An additional 4 to 8 inches of rain is expected across Nicaragua, with isolated amounts as high as 12 inches. Southern and eastern Honduras are forecast to receive 2 to 4 inches of rain, with localized amounts up to 6 inches.
Hurricane Tammy could threaten Bermuda as Tropical Depression 21 soaks Central America
Hurricane Tammy is expected to track near Bermuda this weekend with potential threats of heavy rain and gusty winds. Meanwhile, Tropical Depression Twenty-One in the Caribbean Sea will dump several inches of rain across parts of Central America, increasing the risk of flooding and mudslides.
Tropical Depression Twenty-One has dissipated over Nicaragua, but its remnants will continue to soak parts of Central America with heavy rain, posing the risk of flooding and mudslides. The tropical depression initially developed Monday in the southwestern Caribbean Sea.
It's been a very active hurricane season in the Atlantic Basin, with 21 systems developing and seven strengthening into hurricanes.
Where are the remnants of Tropical Depression 21?
The remnants of Tropical Depression Twenty-One are centered about 130 miles north-northwest of Bluefields, Nicaragua, and are moving toward the west-northwest at 3 mph. Maximum sustained winds are estimated at 25 mph with some higher gusts.

What's the forecast for the remnants of Tropical Depression 21?
The National Hurricane Center (NHC) said Tropical Depression Twenty-One dissipated as it moved inland over Nicaragua on Tuesday morning.
An additional 4 to 8 inches of rain is expected across Nicaragua, with isolated amounts as high as 12 inches. Southern and eastern Honduras are forecast to receive 2 to 4 inches of rain, with localized amounts up to 6 inches.
The heavy rainfall will likely produce flash and urban flooding, along with mudslides in higher-terrain areas.

Atlantic sees active hurricane season in 2023
The season kicked off early with a subtropical storm forming in January in the western Atlantic. That was a possible indication that water temperature trends would be favorable for more tropical cyclone activity later in the season.
Complicating matters for forecasters was the emergence of an El Niño during the usual height of activity.

As a general rule of thumb, forecasters have long said that when an El Niño is in charge in the Pacific, it generally means decreased activity in the Atlantic, but that has not been the case this year.
The 2023 El Niño has not led to cooler water temperatures in the Atlantic, hostile winds across the basin or a host of other issues that tropical cyclones must contend with.
FLORIDA EVERGLADES WATER TEMPERATURES REACH HOT-TUB LEVELS

Significantly warmer water in the key equatorial belt typically correlates with limited hurricane development.

In fact, water temperatures off the coast of Florida broke records this summer when a water quality station in Manatee Bay in Everglades National Park measured a temperature of 101.1 degrees in July.
That temperature may have set a world record, but it's difficult to verify a world sea-surface temperature because of how temperatures are monitored around the world.
