It was just short of a typhoon when it passed us, but it came close enough and was strong enough to cause some headaches.
It came on us quickly and caught many by surprise. But not to the forecasters at the National Weather Service office in Tiyan who had their eye on it since late last week — a disturbance forming out by the Marshall Islands and heading our way.
Layndon Aydlett, NWS meteorologist said: “The GFS model did pretty well with its outlook. This thing developed, was upgraded to a tropical depression SE of Guam near Chuuk State a few days ago, and it continued its intensification for the last couple of days. So in our forecast, we were looking at strong trade winds with the possibility of a tropical cyclone in the vicinity. And that’s pretty much what happened.”
Tropical storm Kammuri’s closest point of approach was about 1 a.m. this morning 140 miles south of Guam, close enough to cover the island with sustained winds of 40 to 45 miles per hour
“We did get tropical storm-force winds overnight. Andersen Air Force base had the peak wind gusts of about 57 knots — that’s about 66 miles per hour — last night at around 9 p.m.,” Aydlett said.
In addition to the winds, there was the rain. By this morning, Kammuri had dumped 4 to 5 inches of rain across much of the island, with more still on the way
“We could be seeing up to 5 to 7 inches. Polaris Point had a lot of flooding. Pago Bay, the highway through there appears to be OK. But there has been a lot of street flooding,” Aydlett said.
It was just short of typhoon strength but strong enough and came close enough to cause some trouble.
“It’s going to continue towards the west with a gradual turn to the west-northwest. And then it’s going to make a tight turn towards the northwest and north. And it’s going to slow down in speed and stall out to our west. It’ll be a typhoon probably by this evening, but the good news for us it’s going to be well west of the Mariana islands.”
