Here's what we can break down:
* hla: This is likely a shortened version of "hola," which means "hello" in Spanish.
* como stas: This is a misspelling of "cómo estás," which means "how are you?"
* k cntas: This is a misspelling of "qué cuentas," which means "what's new?"
* cmo t trata la lluvia: This is a misspelling of "cómo te trata la lluvia," which means "how is the rain treating you?"
A possible interpretation:
The message could be a friendly greeting combined with a question about the weather. The sender is asking the recipient how they are doing and how the rain is affecting them.
To get a better understanding:
* Consider the context. Who sent the message? What was the conversation about before this message?
* Ask for clarification. If you're unsure, it's always best to ask the sender to clarify what they mean.
