Suomi NPP satellite sees compact storm Son-Tinh Headed for Vietnam

July 18, 2018

NASA-NOAA's Suomi NPP satellite flew over Tropical Storm Son-Tinh on July 18 after it crossed over Hainan Island, China and as it moved into the Gulf of Tonkin.

The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite captured a visible image that showed a compact system with a small area of deep and persistent convection.

At 5 a.m. EDT (0900 UTC) the Joint Typhoon Warning Center (JTWC) reported the center of Tropical Storm Son-Tinh was located near latitude 19.0 degrees north and longitude 107.4 degrees east. That's about 173 nautical miles southeast of Hanoi, Vietnam. Son-Tinh was moving to the west. Maximum sustained winds were near 46 mph (40 knots/74 kph).

The JTWC forecasts that Son-Tinh will continue to track westward along the southwestern edge of a subtropical ridge (elongated area) of high pressure. Despite unfavorable vertical wind shear the storm will track through warm sea surface temperatures and slowly weaken.

JTWC expects Son-Tinh will make landfall in northern Vietnam shortly later on July 18 (EDT) and then continue to track inland and dissipate by July 20.

Uncounted
First things first: our very own Latif Nasser has an exciting new show on Netflix. He talks to Jad about the hidden forces of the world that connect us all. Then, with an eye on the upcoming election, we take a look back: at two pieces from More Perfect Season 3 about Constitutional amendments that determine who gets to vote. Former Radiolab producer Julia Longoria takes us to Washington, D.C. The capital is at the heart of our democracy, but it's not a state, and it wasn't until the 23rd Amendment that its people got the right to vote for president. But that still left DC without full representation in Congress; D.C. sends a "non-voting delegate" to the House. Julia profiles that delegate, Congresswoman Eleanor Holmes Norton, and her unique approach to fighting for power in a virtually powerless role. Second, Radiolab producer Sarah Qari looks at a current fight to lower the US voting age to 16 that harkens back to the fight for the 26th Amendment in the 1960s. Eighteen-year-olds at the time argued that if they were old enough to be drafted to fight in the War, they were old enough to have a voice in our democracy. But what about today, when even younger Americans are finding themselves at the center of national political debates? Does it mean we should lower the voting age even further? This episode was reported and produced by Julia Longoria and Sarah Qari. Check out Latif Nasser's new Netflix show Connected here. Support Radiolab today at Radiolab.org/donate.
