5 things to know for April 3: Extreme weather, Auto tariffs, Myanmar earthquake, FAA, Whooping cough

CNN’s 5 Things AM brings you the news you need to know every morning.

President Donald Trump announced sweeping new tariffs on countries and territories yesterday, including some with no economy — or even people. The Heard Island and McDonald Islands in the southern Indian Ocean will apparently have to pay a 10% tariff on goods they send to the US. However, the tiny, uninhabited islands have no exports; they’re home to penguins, elephant seals and seabirds. Here’s what else you need to know to Get Up to Speed and On with Your Day. About 5 million people were under tornado watches early this morning as a wide-reaching storm system moved across the central US. In addition to twisters, days of nearly nonstop rain are expected that could trigger life-threatening, once-in-a-lifetime flooding in the corridor where Arkansas, Missouri, Illinois, Kentucky and Tennessee meet. The line of strong-to-severe thunderstorms has already produced at least 19 reports of tornadoes, including one twister that injured four people and damaged multiple structures in Kentucky, and another that caused a warehouse to partially collapse in Indiana. Wind gusts in the 80 to 100 mph range were reported, as was hail the size of baseballs and tennis balls. President Trump’s new auto tariffs went into effect at 12:01 a.m., which means a 25% tariff on all cars shipped to the US. The Trump administration also plans to roll out a 25% tariff on imports of auto parts no later than May 3. Mexico, Canada, South Korea, Japan and Germany will be the countries most affected by these tariffs. However, since domestic vehicles contain imported parts, it will also cost more to build cars in the US. What does that mean for car buyers? Fewer cars to choose from and higher prices. Used vehicle prices will also climb. While some US automakers may offer temporary discounts to woo consumers to buy American, industry analysts say the tariffs on imported car parts could increase the price of cars made in the US by anywhere from $4,000 to $12,000. How are the tariffs changing your spending decisions and saving habits? Tell us about it. The death toll from the powerful 7.7-magnitude earthquake that hit Myanmar last week has climbed to over 3,000 people. Thousands more have been injured or are missing. Around 500 buildings have completely collapsed and 800 more were partially destroyed. Hospitals are overwhelmed with patients and medical staff are providing critical care inside makeshift tents. As recovery teams continue to search the rubble for survivors — and to remove those who have perished — people living in the city of Mandalay are struggling to live without electricity or clean water. On Wednesday, the UN said that there’s concern such a situation will give rise to diseases. Due to the magnitude of the disaster, the country’s ruling military government announced a temporary ceasefire with armed opposition groups. The truce will reportedly last until April 22.
