First named storm of hurricane season forms in Atlantic – nearly a month early.

A tropical storm warning was issued Friday for parts of North and South Carolina as Ana approached the US coast, kicking up rough surf and rip currents ahead of what was forecast to be a rainy weekend.
The storm formed nearly a month before the Atlantic Hurricane season officially kicks off June 1. The US National Hurricane Center in Miami said Friday that Ana’s maximum sustained winds are near 45 mph (75 kph) with slight strengthening forecast during the next day or so.
The storm is centered about 180 miles (285 kilometers) south-southeast of Myrtle Beach, South Carolina. The Hurricane Center says it’s been nearly stationary over the last few hours but is expected to move north-northwest later in the day.
The tropical storm warning is in effect from the south Santee River in South Carolina to Surf City, North Carolina.
Rain is a concern because the system is moving so slow and won’t clear out quickly. Ana is expected to deliver 2 to 4 inches of rain over the weekend, with some areas getting up to 6 inches.
Ana is currently a subtropical system, meaning it has characteristics of both a tropical storm, which gets its energy from warm ocean waters, and a traditional storm system driven by temperature changes.
Forecasters are also warning people to avoid dangerous surf and rip currents being kicked up by the storm. Some isolated flooding is also expected in some areas along the coast.
“We’ve lost a lot of lives in rip currents, let’s try not to do that this weekend,” said Hurricane Center director Rick Knabb.
May storms aren’t unusual, with one forming every few years or so, Knabb said. But Ana marks the earliest subtropical or tropical storm to form in the Atlantic since another storm named Ana in 2003, the Hurricane Center said in a tweet.

Tropical Storm Ana weakens off South Carolina but beaches remain dangerous.
Tropical Storm Ana weakened slightly as it lumbered just off the coast of South Carolina, sending pounding surf crashing against Atlantic beaches as it prepared to bluster inland, forecasters said.
The US National Hurricane Center in Miami said Ana was centered at 5 am EDT about 5 miles south of North Myrtle Beach, South Carolina, and packed top sustained winds of 45 mph.
Ana, a surprisingly early tropical storm that emerged ahead of the official 1 June start of the Atlantic hurricane season, was moving to the north-northwest at a plodding pace of about 5 mph.
Hurricane specialist Dave Roberts said the storm would be blowing ashore Sunday morning in an area between Myrtle Beach, South Carolina, and Wilmington, North Carolina.
The storm was kicking up 11- to 12-foot seas – as recorded by offshore buoys – and the dangerous surf was a worrisome aspect of the storm, he said. He advised people to stay away from the water.
“It’s about rough surf. People need to stay off the beach for sure,” Roberts told the Associated Press by phone from the hurricane center.
Although the Atlantic season doesn’t formally start until 1 June, early surprise storms are not all that unusual every few years or so, the center said. There were two May tropical storms in 2012, for instance.
A tropical storm warning, meanwhile, remained in effect from the South Santee River in South Carolina to Cape Lookout, North Carolina. Forecasters said the storm, once it hit cooler waters, would weaken further and head inland while breaking up.
