If you’re living on Hawaii’s Big Island, the timing of Tropical Storm Moke feels like a cruel joke. After barely a week to process the damage left behind by Hurricane Lala—which wiped out homes, shredded infrastructure, and dumped over 40 inches of rain in some high-elevation areas—the last thing anyone wanted was another system on the radar.
But here we are. Moke isn't a repeat of the high-wind catastrophe that caused such widespread destruction just days ago, but don't let that fool you into thinking it's a non-event. The real danger here isn't the wind. It’s the water.
Why This Storm Is Still Dangerous
Meteorologists are being clear: Moke is tracking south of the islands. That sounds like good news, right? It's not necessarily. The problem is that the storm is pulling massive amounts of moisture toward the islands, targeting areas that are already completely saturated.
When the ground is this waterlogged, it cannot absorb more rain. It basically turns into a slip-and-slide. Even moderate rainfall can trigger flash floods and mudslides when the soil has no capacity left. If you live in windward or southeast districts like Puna or Kaʻū, you’ve already seen what happens when the land gives way. You know the roads turn into rivers.
Current forecasts for the Big Island are calling for 5 to 10 inches of rain, with isolated spots potentially seeing up to 15 inches. For context, that’s an immense amount of water to dump on a place that’s still digging out of the mud from Hurricane Lala.
Managing Your Safety During Moke
I’ve seen enough weather events in these islands to know that complacency is your biggest enemy. We tend to hear "it's just a tropical storm" and think we can go about our weekend business. Don't.
If you’re on the Big Island, you need to take these steps right now:
- Audit your immediate surroundings. If you’re in an area that flooded during Hurricane Lala, assume it will flood again. Don't wait for a formal evacuation order if you already feel unsafe.
- Check your supplies. Gov. Josh Green and emergency officials are recommending at least 14 days of food, water, and medicine. Supply chains on the Big Island are still recovering from the last storm; don't bank on stores being fully stocked or accessible.
- Stay off the roads. Flash flooding often happens fast. You don't want to be the person who gets trapped in their car because a small stream turned into a raging torrent in minutes.
- Monitor the wind, but watch the surf. While the wind field for Moke isn't expected to be as aggressive as a major hurricane, the swells being generated are no joke. Expect dangerous rip currents and high surf along the south and east shores. Stay out of the water.
What You Should Actually Expect
The National Weather Service is pointing out that Moke is weaker than the previous storm, and the wind field isn't nearly as broad. That’s a relief. We shouldn't expect the same level of widespread power grid collapse or structural failure we saw with Lala.
However, the threat to life and property is very real because of the pre-existing conditions. This is a secondary disaster. It’s the kind of situation where a local community might think they're in the clear because the "center" of the storm missed them, only to find their driveway gone and their lower floor flooded because of a localized deluge.
Follow the guidance from the Central Pacific Hurricane Center and the Hawaii County Civil Defense. If they tell you to prepare for bad weather, they aren't trying to be alarmist. They’re dealing with land that is literally falling apart.
Don't wait until the power goes out or the rain starts hitting the roof at ten inches per hour to make a plan. Pack your go-bag, secure your loose outdoor items, and keep your phone charged. If you live on the windward side, stay home and stay alert. This isn't the time to test your luck.
