Meaning
An open umbrella with raindrops falling on it, clearly signalling that it is raining right now. The drops bouncing off the canopy make it feel lively rather than gloomy.
It is the go-to rain emoji for wet commutes, monsoon seasons and cosy indoor days: “Pouring outside ☔ let’s just order in.” Compared with ☂️ and 🌂, this is the one that says the weather has actually turned wet.
