Key Factors
- 01 Active Wind Advisory until 12:00 PM EDT for north winds 15–20 mph with gusts as high as 40–50 mph, which can make driving difficult and increase risk of falling branches/power disruptions.
- 02 Frequent rain show ers with very high precipitation chances (about 67–93% through late morning and afternoon, and 73–99% from early evening into the night).
- 03 Reduced visibility risk from steady rain (relative humidity near 100% in the hourly data).
- 04 Winds remain breezy all day (roughly 14–23 mph through the daytime and into the evening), increasing difficulty for high-profile vehicles and affecting traction on wet roads.

Recommendation
Avoid driving during the Wind Advisory period, especially the morning commute: 7:00 AM–12:00 PM EDT. If travel is necessary, limit driving to the least-bad evening window with relatively lower rain chances: 3:00 PM–4:00 PM EDT; otherwise expect heavy rain risk from about 6:00 PM onward.
