Philadelphia faces a severe thunderstorm warning Tuesday that could trigger flash flooding within minutes. The National Weather Service issued the alert as a line of storms moves eastward from Western Pennsylvania, where a separate severe thunderstorm watch was already in effect for Allegheny County. Residents underestimate how fast a single storm can overwhelm city drainage systems. There is no time to react. The difference between a “watch” and a “warning” is life and death.
