FAQ: Your Questions Answered
1. Is this a hurricane or tropical storm?
Nope! Just a slow-moving low-pressure system with tons of moisture. No wind damage expected — just rain, rain, and more rain.
2. My basement floods sometimes. Should I worry?
Yes. If you’re in a flood-prone spot (near river, low yard, past issues), move valuables up now. Check sump pump. Have a wet vac ready.
3. Can I still go to work/school Wednesday?
Probably — but check morning updates. If flash flood warnings are active for your town, stay home if you can. Evening commute will be worst.
4. What’s the difference between a "Watch" and a "Warning"?
- Watch = Conditions are right for flooding. Be ready.
- Warning = Flooding is happening NOW or imminent. Take action!
5. When will it finally stop raining?
Thursday night things taper off. Friday looks dry and brighter. But — another system might bring rain by Monday. Stay tuned!
