It’s now Super Typhoon Mawar and it's already predicted to be a potentially catastrophic and devastating event for Guam.

The storm is a strong category 4, low-end category 5 storm, with potential to intensify.

As of 7 p.m., the Guam National Weather Service reported the storm strengthened with maximum sustained winds increasing to 155 mph.

Mawar is moving at 8 mph and is expected to make a slight turn northwest.

"We are looking at the high potential for a direct hit and passage of a Super Typhoon on Guam. This will be the first time in many years. This will be a benchmark storm that many folks on this island have not experienced," said Landon Aydlett, local meteorologist. "Weather, winds conditions across the island will steadily deteriorate as we go through the evening and overnight hours. They will significantly worsen through the morning on Wednesday, reaching peak intensity with a likely direct passage of a super typhoon around midday, early afternoon Wednesday, and then rapidly subsiding winds down to tropical storm force winds by Wednesday evening and then persisting through the overnight hours."

He adds the landscape for Guam on Thursday will become radically altered.

A typhoon warning remains in place for Guam and Rota.

Experts said the time to prepare is up.

The community is being told to seek immediate shelter, if you have not done so already. The onset of damaging winds is expected tonight, so find someplace safe before it’s too late.

Super Typhoon Mawar is expected to make a direct hit for Guam.

The Joint Information Center warns everyone that this is a very serious situation with steadily deteriorating conditions. The triple threat of category 4 typhoon-force winds, torrential rains, and life-threatening storm surges are all expected for Guam.
