Red Rainstorm shuts down the whole city at 7:40am, no warning, half of Hong Kong already on the bus to work. Whole-day classes cancelled, offices scrambling, and everyone's group chat turns into a weather forecast at once. That's Thursday in Hong Kong for you.

Meanwhile the government's other big morning move: five people arrested for sedition over bookstore stock. Not knives, not bombs, books. RTHK says police raided stores and pulled in five under the sedition law, and the Washington Post is now writing about Beijing "widening" its crackdown on booksellers, which is the kind of headline that used to be about mainland China and is now, once again, about us. Funny thing about a rainstorm warning is it tells you exactly what's dangerous and exactly when it'll pass. A bookshelf doesn't get that courtesy. Nobody's raising a black flag over which books cross the line, so shop owners are left guessing, and guessing is worse for business than any rainstorm. At least with the weather you know to bring an umbrella.
