My backyard tomatoes keep splitting after a good rain—what’s the best way to prevent it?

I planted cherry tomatoes in my backyard about two months ago, and they’ve started producing nicely. The problem is, every time we get a heavy rain, a bunch of tomatoes split open on the vine. I’ve tried watering less frequently to avoid sudden changes, but with unpredictable weather, it’s tough to keep the moisture steady. I really want to enjoy fresh tomatoes without losing half the harvest to splitting. Has anyone dealt with this before? What techniques or products have you found effective to protect tomatoes from cracking after rain? Also, is there a specific tomato variety that’s more resistant to this issue?
