Dexter formed almost two weeks earlier than the historical average for the fourth named storm of the Atlantic hurricane season. The average date for the fourth storm is Aug. 15. Historically, the first hurricane develops in the Atlantic Aug. 11.
The National Hurricane Center is also tracking two other systems showing some potential for development: one off the Florida and the other a tropical wave moving off the coast of Africa.
The tropical wave in the central Atlantic could become a tropical depression later this week, according to the National Hurricane Center.
Next up will be Erin and Fernand.

Will Dexter become a hurricane? Will it threaten Florida?
Dexter is not expected to impact Florida or the U.S. as it moves northeast into the northern Atlantic, according to the National Hurricane Center.
While some slight strengthening is possible, Dexter is expected to remain a tropical storm as it encounters wind shear and dry air.
What tropical waves, disturbances are in Atlantic basin now? How likely are they to strengthen?
First tropical wave: A broad area of low pressure is forecast to develop in a day or two several hundred miles off the coast of the southeastern United States. Some gradual development of this system is possible duringthe middle or latter portion of this week as the system moves slowly westward to northwestward.
Formation chance through 48 hours: low, near 0 percent.
Formation chance through seven days: low, 30 percent.
Second tropical wave: A tropical wave located just off the west coast of Africa is currently producing minimal shower activity. As the wave moves west-northwestward over the next few days, environmental conditions are forecast to become favorable for gradual development. A tropical depression could form by the latter portion of this week as the system continues moving generally west-northwestward across the central tropical Atlantic.
Formation chance through 48 hours: low, near 0 percent.
Formation chance through seven days: medium, 50 percent.
What do the colored, hatched areas on the NOAA map mean?
The hatched areas on the National Hurricane Center's tropical outlook map indicate "areas where a tropical cyclone — which could be a tropical depression, tropical storm or hurricane — could develop," said National Hurricane Center Deputy Director Jamie Rhome.
The colors make it visibly clear how likely a system could develop, with yellow being low, orange medium, and red high.
The National Hurricane Center generally doesn't issue tropical advisories until there is a named storm, but there is an exception.
"If a system is near land and there is potential for development, the National Hurricane Center won't wait before it issues advisories, even if the system hasn't become an actual storm. This gives residents time to prepare," Rhome said.
Who is likely to be impacted by Tropical Storm Dexter, tropical waves out there?
Tropical Storm Dexter is not expected to impact Florida or the U.S. as it moves into the northern Atlantic.
It's too early at this time to determine if there will be any impact to Florida or the U.S. from the tropical waves.
➤ Excessive rainfall forecast
Forecasters urge all residents to keep an eye on the tropics and to always be prepared.
Buy hurricane supplies tax free in Florida
Officials repeatedly warn Florida residents the time to prepare for a hurricane is before a storm is approaching, when shelves are full stocked and you aren't battling crowds all rushing to the store at the same time.
In prior years, Florida residents took advantage of one or two sales tax holidays to save money on hurricane supplies ranging from batteries to generators.
On Aug. 1, certain supplies became permanently tax free in Florida.

Goodbye fall, back to summertime
MYRTLE BEACH, S.C. (WBTW) — Fall-like feels are gone! Today's temperatures are 4 to 9 degrees warmer than yesterday morning, and the humidity is back to summertime levels. High temperatures will remain below average in the mid-80s, but it will feel like the low 90s due to the higher humidity. Scattered light showers will be periodic throughout the day. There were no storms yesterday, but with the higher humidity, an isolated thunderstorm is possible. Temperatures will remain slightly below average for most of the workweek. Nighttime temperatures are closer to normal in the low and mid-70s overnight, but the afternoon temperatures will be slightly below average in the mid-80s. No day this week will be perfectly dry; rain is expected to be scattered today through Thursday, and it will be rainier on Friday as an area of low pressure moves north, close to our area. We will monitor that area of low pressure, expected to form off a stalled front, for a 30% chance of tropical development. Tropical update Out in the tropics, Tropical Storm Dexter formed off the stalled front on Sunday. Dexter has winds of 40 mph and is expected to remain a weaker storm as it heads northeast into the North Atlantic and away from the continental U.S. There are two other areas of interest. A tropical wave off of Africa will be traveling across the Atlantic for the next seven-plus days. This is not something that requires our immediate attention, but just know it is out there. It is likely to be a named storm eventually, but organization will be slow and is not likely to occur this week. The next name on the list is Erin. The seven-day likelihood of development is 40%. A closer area of interest has a 50% chance of developing (the one expected to bring more rain on Friday). It is to our east-southeast and is expected to move northwest into central, coastal North Carolina on Friday. Regardless of whether it is 'tropical' or just an area of low pressure, it will bring rain to our area, primarily on Friday. The seven-day rainfall totals will be 2 to 4 inches.

Tropical area of interest off Southeast coast has 40% chance of development; will bring rain to Grand Strand
MYRTLE BEACH, S.C. (WBTW) — A tropical area of interest several hundred miles off the coast of the Southeast has a 40% chance of development and is expected to bring rain to the Grand Strand on Friday, according to the National Hurricane Center. 'A weak surface trough currently located several hundred miles off the coast of the southeastern United States is expected to form an area of low pressure in a day or so,' the NHC's 8 a.m. Tuesday update reads. 'Thereafter, environmental conditions appear favorable for gradual development of this system, and a tropical depression could form by the latter portion of this week or weekend as the low initially moves slowly westward, but turns more northward by this weekend.' The area is to our east-southeast and is expected to move northwest into central, coastal North Carolina on Friday, News13 meteorologist Hannah Rahner said. Regardless of whether it develops into a tropical system or is just an area of low pressure, it is expected to bring rain to the Grand Strand, primarily on Friday. Rahner said Tuesday morning the seven-day rainfall totals will be 2-4 inches. Count on News13 for updates. * * * Caleb is a digital producer at News13.

Tropical Storm Ivo forms in the eastern Pacific and could impact coastal Mexico, forecasters say
MIAMI (AP) — Tropical Storm Ivo formed Wednesday in the eastern Pacific Ocean and was expected to bring rain and rough surf to parts of Mexico's southwest coast, forecasters said. Ivo had maximum sustained winds of 40 mph (65 kph) and was centered about 195 miles (310 kilometers) south-southeast of Acapulco, according to the National Hurricane Center based in Miami. Forecasters said Ivo is expected to be near hurricane strength by the end of the week as it spends a few days moving offshore, and generally parallel to the coast, before turning west away from land. No coastal watches or warnings were in effect as Ivo moves west-northwest at 22 mph (35 kph). But large ocean swells kicked up by Ivo could cause life-threatening surf and rip currents, the hurricane center said. The storm also threatened flash flooding and was expected to dump 2 to 4 inches (5 to 10 centimeters) of rain with isolated totals of up to 6 inches (15 centimeters) in spots around parts of the Mexican states of Guerrero, Michoacan and southwestern portions of Oaxaca through Saturday. Ivo was the second tropical storm in the eastern Pacific, joining Tropical Storm Henriette. On Wednesday, Henriette had maximum sustained winds of 50 mph (85 kph) and was located 1,555 miles (2,505 kilometers) east of Hilo, Hawaii, and moving west. In the Atlantic, Dexter remained a tropical storm but was forecast to become a powerful extra-tropical cyclone.
