LAS VEGAS (KLAS) — People across the country and in Las Vegas are mobilizing to help as Dorian strengthens and threatens to be a Category 4 hurricane when it makes landfall likely on Labor Day.

With 86-degree water as fuel and favorable moist winds, there’s little to prevent the storm from powering up Friday. On top of that, the warmer-than-normal water is running deeper than usual, adding more fuel. The hurricane center predicts Dorian will make landfall on Labor Day as a Category 4 storm with 130 mph winds.
