The National Hurricane Center is expecting to see the 18th tropical depression of the year by as early as Wednesday afternoon, it said in the 2 p.m. EDT update.
Meanwhile, tropical depressions Peter and Rose seemed to almost be joined together at the hip as they entered the Atlantic together. They degenerated together and they may dissipate together too.
First, a tropical wave southeast of the Cabo Verde Islands has better circulation and is becoming more defined, the NHC said. The system is moving west at about 10 to 15 mph and heading into an ideal environment of tropical growth where the NHC says it has a 100% chance of becoming a tropical depression, and could do so by Wednesday afternoon.
If it grows into a tropical storm, it would receive the name Sam.
As for Peter and Rose, they both formed into tropical storms Sunday and both degenerated into depressions Tuesday. Neither is a threat to land at this time, and both are forecast to dissipate before the end of the weekend.
As of 11 a.m., Tropical Storm Peter had sustained winds of 35 mph and was located about 225 miles north of San Juan, Puerto Rico, moving west-northwest at 7 mph.
It is of no immediate threat to land and is expected to turn northwest and north into the open Atlantic this week. The NHC warns of some rainfall that could lead to urban flooding in the Leeward Islands, Puerto Rico, and parts of Hispaniola, the NHC said.
Meanwhile, Tropical Storm Rose has 35 mph sustained winds and is located about 1,115 miles from the Cabo Verde Islands, moving northwest at 9 mph. Forecasters expect Rose to slow down into Thursday as it moves north into the open Atlantic. The system should fizzle into remnants Friday night or Saturday.
Also, to the north, the remnants of Odette remain a storm-force non-tropical low-pressure system located 500 miles west-northwest of the Azores. It could acquire some subtropical or tropical characteristics by the end of the week as it moves east and then south over warmer Atlantic waters. However, as the system south this weekend it is expected to encounter hostile hurdles in the form of strong upper-level winds preventing reformation. The NHC gives it a 40% chance of reformation in the next two days and a 60% in the next five.
So far, the 2021 Atlantic hurricane season with 17 named systems is the third most active behind 2021′s record year and 2005.
