How In-Fa is behaving
The observation records winds of 56 km/h, gusts of 64 km/h and a pressure of 1,004 mb. A gust is a brief peak in wind speed. The file contains only this one measurement, so it cannot show a pressure trend or whether the winds are increasing or easing. The storm's recorded movement is 6 km/h on a 140° bearing; a bearing measures direction clockwise from north, and 140° points southeast. One position cannot establish whether the storm's motion has been steady or has changed.
How to track In-Fa
Turn on the tropical storm tracks layer in RainViewer to see the recorded path for Thirty. Track points show the storm's category at each recorded position: tropical depressions are cyan, tropical storms blue, category 1 yellow, category 2 amber, category 3 orange, category 4 red and category 5 dark red. Thirty's recorded point corresponds to tropical depression cyan.
With only one reading on file, the track cannot show a previous direction or speed change. Compare any later recorded points with this 140° bearing, 6 km/h movement, wind and pressure to see what has changed in the observations. Open RainViewer on Google Play or the App Store to follow the track. RainViewer does not provide official warnings; check your national weather service for that information.
Storm FAQ
Why are tropical cyclones given names?
Names give tropical cyclones distinct identifiers, making it easier to discuss and distinguish storms. The names come from regional lists.
What is the difference between wind speed and gust speed?
A gust is a brief peak in wind speed, while the wind figure describes the storm's recorded wind speed. Thirty's single reading lists 56 km/h winds and 64 km/h gusts.
