NWS monitors systems as typhoon season rolls on

Posted: Sep 11, 2018 4:05 PM +10:00 Updated:

Although Typhoon Mangkhut has moved away from the Marianas, the National Weather Service continues to collect data to test the force of the storm.

Usually, NWS meteorologists send up two weather balloons a day, but during Typhoon Mangkhut, meteorologists posted at the NWS in Tiyan sent four balloons into the storm.

Ken Kleeschulte, a lead meteorologist at NWS explained that a balloon is the size of a bus when it pops to read the weather.
“When we have something like this going on because the models actually run every six hours but during the intermediate times they don't get any extra input,” he said. “So when we have something like this we put in the extra input and we send up an extra balloon so that's what you got to see and that gives extra data so it can do a better job for our forecast.”

To track even more data, meteorologists are now in route to Rota, our neighboring island north of Guam that was caught in the eye of the storm.

“We usually send a group of people to the islands affected heaviest with the storm, we want to look at where the damage is how significant the damage is to really verify our winds, measurements and also our forecast,” Landon Aydlett , also from NWS, said. “So we do that with every storm passage.”

Aydlett previously predicted the Typhoon could be the "worst storm Guam has seen in over a decade" since Supertyphoon Pongsona, a possible Category 5.

Conditions, however, were less damaging than expected.

“On Guam we experienced Category 1 conditions we did have peak wind at Andersen Air Force Base of 82 mph,” Aydlett said. “This situation looked pretty grim back on Friday when the first advisory's are coming through. “The model's were intensifying this pretty gradually rapidly through the weekend. Thank God that did not happen that west-southwestward shift happened 48 hours later than the module was forecasting. That put the storm more over a passage of Rota which we saw last night.Though Guam was prepared, he said also seeing the CNMI ready gave a good sense of security.

But with typhoon season continuing until December, NWS remains on the lookout for storms. Like this disturbance between Kosrae and the Marshall Islands. Though at the time, they don't expect any development with this system.

But as we saw with Typhoon Mangkhut anything can happen.
