According to the National Hurricane Center (NHC), the subtropical storm Theta set a new record for the most named storms in a hurricane season in the USA.
Theta, which developed on Monday evening, marked the 29th named storm in the Atlantic hurricane season 2020, breaking the previous record from the 2005 season, which had 27 named storms.
Theta follows Tropical Storm Eta, which hit the mainland on Sunday night in Lower Matecumbe Key of the Florida Keys with torrential rainfall and sustained winds of up to 65 miles per hour (mph).
Eta was reported to be immediately north of the Yucatan Channel, while the risk of flooding over South Florida and the western region of Cuba remains, according to NHC, at 3:00 a.m. CST on Tuesday.
“Heavy rainfall from Eta will continue over western Cuba and South Florida today [Tuesday] and tonight. Further flash flooding and urban flooding, especially over previously flooded areas, will be possible in South Florida. Flash floods and urban flooding will also be possible in western Cuba.
“Eta could approach the Gulf Coast of Florida as a tropical storm later this week, possibly bringing the effects of rain, wind and storm surge. Interests in the area should continue to follow the progress of Eta and update the forecast this week,” NHC stated.
It is predicted that Eta will gradually strengthen by early Thursday. However, “after this time, increasing shear and drier air at mid-altitude will likely lead to a weakening of Eta,” the NHC said. The speed of this weakening is quite uncertain, and much will depend on how much the eta can strengthen again in the coming days,” the NHC added.
Subtropical storm #Theta developed in the Northeast Atlantic this evening, the 29th named storm of the Atlantic hurricane season 2020.
This breaks the single season record for the most named storms of the 2005 hurricane season.

Theta is expected to remain in the East Atlantic region for the next few days. On Tuesday at 9:00 GMT it was reported that the storm is moving eastward at nearly 12 miles per hour, with east-to-northeast movement across the East Atlantic expected in the coming days.
“The maximum sustained winds are 85 km/h (50 mph) with higher gusts. Only a slight change in strength is expected in the coming days. Winds of 40 mph extend up to 115 miles (185 km) from the center outward,” the NHC noted.

Eta and Theta could possibly be joined by a third storm in the central Caribbean, where a low-pressure system could develop this week.
Weather conditions could be favorable for the low to develop into a tropical depression or storm as it moves westward this week or over the weekend, the Weather Channel reported.
The likelihood of a development in the coming days is low to moderate, which AccuWeather’s meteorologists believe could pose a potential threat to Central America, Jamaica and/or Cuba.
The latest count of named storms has shaken the total number of 13 to 19 named storms for the Atlantic hurricane season 2020 previously forecast by the National Oceanic Atmospheric Administration’s (NOAA) Climate Forecasting Center.
