The National Hurricane Center will be providing new warnings about storm surge starting next year. 

In the past, hurricane warnings have been issued based on wind predictions. Now, storm surge will be taken into account as well.

Jamie Rhome of the National Hurricane Center says that is especially important for states like North Carolina.

"I can't just say that storm surge is going to be bad in North Carolina because in some places it is going to catastrophic and in the next community over it might not be so bad," Rhome says.

Category one Hurricane Arthur has maximum sustained winds of 80 miles per hour.

Hatteras Island residents have begun a mandatory evacuation this morning, and a State of Emergency has been issued for all of Dare County. Hyde County has issued a voluntary evacuation for Ocracoke Island for 2 p.m. today.

National Weather Service Meteorologist Lara Pagano said North Carolinians can expect to feel the effects of the hurricane's outer bands today.

It would be easy to look at the newest round of floodplain maps and think that we've been wrong about the Outer Banks all this time.

For the past decade, the standard line has been that things on the coast are getting worse. Sea levels are rising; the shoreline is eroding; flooding is becoming a bigger threat. Flood risk is largely determined by a series of maps produced by the state of North Carolina. Those maps then make their way to FEMA, who administer the National Flood Insurance Program. Basically, the higher your risk, the more you pay in flood insurance.

This month, North Carolina launched FRIS, the Flood Risk Information System. It's the first system of its kind in the country to put all of the state's flood risk data, county-by-county, building-by-building, into one digital initiative.

It's not the prettiest map ever designed, but it's full of all sort of information that used to require a lot of manpower to produce for whoever wanted it.

Engineers in Raleigh's Storm Water Utilities Department are planning to replace dams protecting some capital city neighborhoods.  Each project is expected to begin next year with costs into the millions of dollars.

Researchers at UNC-Chapel Hill are using storm surge data to give coastal communities a better idea of what they can expect during hurricanes. 

The university's Renaissance Computing Institute, or RENCI, has a network called the Surge Guidance System.  It gathers intricate details of ocean activity to calculate where, how and when storm surge will affect certain areas.

Orange County continues to recover from weekend flooding, and officials are trying to secure relief funding for those displaced.

At a news conference today, Chapel Hill officials said close to 130 residences are unlivable due to water damage from weekend rain. It's unclear when, or if, people who lived in those units can go back home.

Residents of Orange and Durham counties are cleaning up after torrential rain led to flood waters several feet deep. 

Officials in Chapel Hill say rescuers evacuated at least 40 people Sunday from flooded homes and vehicles.  They were taken to a Red Cross shelter at Smith Middle School.

Current and former members of the military want to talk about how climate change could be threatening national security. 

A public meeting in Fayetteville tonight will include discussions about evidence linking climate change to a rising risk of stronger natural disasters.  Spring Lake mayor Chris Rey is one of the speakers at the meeting and a former Army captain.  He says storms that cause widespread damage divert military resources, leaving the impacted areas more vulnerable.
