High pressure over the Great Basin promotes partly cloudy to mostly sunny skies into the desert southwest. In the tropics, Hurricanes Lester and Madeline march towards Hawaii.

Merchants boarded up shop windows Wednesday along Hilo Bay, and shoppers snatched supplies of food and water from grocery store shelves as what could be the first hurricane to hit Hawaii in a quarter-century neared the island.

The National Weather Service said Hurricane Madeline had weakened but remained on track to hit Hawaii’s Big Island early today.

Officials urged residents to expect hurricane conditions and to take steps to protect themselves and their property.

“Hopefully our roofs stay on, and our houses don’t float away or get blown away,” said Big Island resident Mitzi Bettencourt, who boarded up walls of glass windows at her brother’s oceanfront home. “It’s like, ‘Oh my God, are we going to get flattened or what?’”

Elsewhere, the National Hurricane Center said Tropical Storm Hermine had formed in the Gulf of Mexico and was centered about 400 miles from Tampa, Fla. It was expected to pick up speed and approach the northwest Florida coast this afternoon. A warning was dropped about a tropical depression that had been moving toward North Carolina.

In Hawaii, Peggy Beckett, a retiree and beekeeper, stopped at a Hilo supermarket to pick up onion bagels, cheese, cold cuts and salad to add to her canned food at home. She also has a cooler with ice plus a portable burner and batteries to get her through the storm.

Noting the lines of people at the market, Beckett said people were getting prepared but weren’t panicking.

“There’s always a lot of disbelief on the island that the storms will really be as big and bad as forecast,” she said, noting that she and her partner had taken precautions to protect their beehives.
