A number of hazards are expected to start off the week. Heavy rain and strong to severe storms may produce flooding and damaging winds in the Mid-Atlantic. Heavy rain and flooding are possible in the Great Lakes. Locally heavy rain may result in flooding in parts of the Southwest with a few severe storms in Arizona. Impacted Lanes: Highway 93, State Route 96, State Route 71 and State Route 97 in Arizona
Flood Advisory remains in effect until Late Tonight MST
- Flash flooding caused by excessive rainfall is possible. Thunderstorms are anticipated to develop over portions of south-central Arizona during the day Monday and produce locally heavy rainfall and in turn create the potential for flash flooding.
- Impacts: Flash flooding will be possible in creeks, normally dry washes, swimming holes and over recently burned areas. Low-water crossings could also experience flash flooding, which would create deadly travel conditions. Highway 93 between mile markers 149 and 176. State Route 96 between mile markers 0 and 16. State Route 71 between mile markers 90 and 94. State Route 97 between mile markers 156 and 166.
Coastal Flood Advisory remains in effect until 8 PM EDT this evening
- Up to one half foot of inundation above ground level in low lying areas due to tidal flooding.
- Impacts: Tides one to one and a half feet above normal. If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth.
