Rain Without Warning

Inés Marchetti had been the meteorologist aboard the *Slow Rain* for eleven years, and in eleven years she had never missed a forecast. No one held it against her: on a ship four kilometers long, with a sky of panels and clouds pumped in through valves, getting it right seemed the least anyone could ask. Still, people liked to listen to her. Every night at nine she appeared on the screens in the dining halls and said, "Tomorrow, light drizzle in the green sector starting at four. Those of you in the orchards, bring umbrellas." And at four it rained, and the orchard workers had their umbrellas.

She had known the secret since her second year. The models she used predicted nothing: they read a calendar. She had found it buried in the core of the climate system, a two-hundred-year file with one line per day, and on each line the wind, the temperature, the clouds, and the rain. The founders had written out the weather for the entire voyage in advance. Inés told no one. She thought it did people good to believe the sky had a mood of its own, and she preferred being the voice of that mood to being its notary.

On Tuesday of day 72,996 she opened the file to prepare the broadcast and saw that the calendar was running out. Four days remained until the destination orbit. The last line written was for day 73,000, with its usual drizzle. After that, in place of numbers, there was a note in the clumsy syntax of the comments programmers leave for themselves: "From here on, the engine runs free. Let no one forecast it."

Below it, in the metadata, she found a second note, longer, signed by someone named Ortega: "We gave them a world that gives warning. Down there it won't. The last days of the journey will be real weather, the kind that comes from the physics of the hull, the heat of the kitchens, a thousand people breathing. Let them learn with their bodies what they could never learn from data."

Inés stayed awake the whole night. She could, of course, feed the engine the ship's actual state and run a simulation. She would get a decent approximation, perhaps eighty percent accuracy. It would be easy to go on being the woman who never gets it wrong. At seven in the morning Captain Rubén called her, in the voice of someone who hadn't slept either: people were nervous, they wanted to know what the weather would be on the day of the descent, whether they could go out and see the new sky. "What should I tell them?" he asked.

"Nothing," she said. "I'll tell them myself."

At nine that night she appeared on the screens, as always. She gave the three days that were left: light drizzle, green sector, four in the afternoon. Then she paused, a pause no viewer had ever seen from her.

"From the fourth day on, I don't know," she said. "No one does. It's the first forecast I can't give you, and I think it's the one that matters most to you."

A long silence fell over the dining halls. A little girl was heard asking whether that meant the sun might come out. "It might," Inés answered. She had heard the girl over the open channel of a nearby screen, and she was surprised at how good the word tasted.

The three days went by with their punctual drizzle, and people lived them with a new attention, watching the drops the way one watches a farewell. The fourth day dawned with nothing planned. At noon, without any valve having decided it, the air in the green sector thickened, the ceiling darkened, and a storm broke such as no one had ever heard, with a thunderclap that rattled the cups in the dining halls. People ran outside without umbrellas, frightened and laughing, their drenched faces turned upward.

Inés stood in the middle of the orchard, soaked to the bone, not knowing whether the storm would last a minute or an hour, and she understood that for the first time in eleven years she was inside the weather instead of reading it.

When, two weeks later, they finally descended to a planet with a true sky, no one carried an umbrella or missed having one. Everyone walked looking up, with the care of someone just beginning to learn to read. That night, in her first broadcast from solid ground, Inés said only: "Tomorrow, I don't know. Go out and see it."
