Recommendation
Drive during the safer windows: (1) Morning: about 7:00 AM–11:00 AM (sunny, 0% precip). (2) Evening: about 4:00 PM–7:00 PM (only ~1% precip early evening). Avoid late night and the highest-risk period: roughly after 10:00 PM, and especially 2:00 AM–5:00 AM when patchy fog and storms are expected.
