In a true SHTF scenario, or natural disaster, cops aren't going out on routine patrol and responding to calls.
They will be worried about a city-wide evacuation, manning roads to make sure both directions are now one-way, away from the disaster. Some may be in the urban areas to deter looting. But cops are only human, aren't indestructible beings who are immune to the effects of nature, and they won't be dispatched out to check on an alarm call when a hurricane is blowing. My agency will suspend calls for service when the wind gets too high, even in "only" a tropical storm".
