Hurricane Florence strengthens to potentially catastrophic Category 4 storm

Hurricane Florence strengthens to potentially catastrophic Category 4 storm

That cone is a graphical representation of a storm's probable track, according to the National Hurricane Center.

The National Hurricane Center is advising people in the hurricane's path to prepare for potentially life-threatening storm surges, freshwater flooding and damaging winds as Florence impacts the United States this week.

Helene, a category-2 hurricane with wind speeds topping 110mph, is now hurtling north-westwards across the Atlantic but set to make a u-turn away from America at the end of this week.

The devastation from 17 named storms, 10 hurricanes and 6 six major hurricanes reached near apocalyptic proportions in some regions, causing an estimated $282billion worth of damage. "Its impacts may be felt much deeper in the USA, including in most of Virginia".

Feltgen said it's important that people don't get "hung up on the cone", and prepare for the possibility of impacts in areas outside of it.

"Satellite imagery indicates that the maximum sustained winds have increased to near 105 miles per hour (165 km/h) with higher gusts", the NHC said in its latest advisory.

Isaac, a weakening Category 1 hurricane, is much farther south, and is facing the same winds that threatened to rip Hurricane Florence apart. She grew up on the shore, and says this will be only the second time she's evacuated.

On its current track Florence is expected to slam the Carolinas and Virginia the hardest - and all three states have issued emergency declarations to speed preparations.

In coastal Charleston, South Carolina, city officials offered sandbags to residents. But experts are urging people along the eastern seaboard to be especially cautious. Maximum sustained winds are around 75mph; strengthening is expected over the next day or two but it's expected to weaken as it approaches the Lesser Antilles. "They're coming in and buying water and plates, and that's about all they're buying". Ilija Cesal told the newspaper he wouldn't worry about buying extra water or other supplies for a few more days.

The US navy has ordered ships at its major base in Hampton Roads, Virginia, base to put to sea, saying "the forecasted destructive winds and tidal surge are too great to keep the ships in port". The storm is anticipated to move near of over the central Lesser Antilles on Thursday and into the eastern Caribbean Sea late Thursday night at near hurricane strength. This appears to be no threat to land.
