The stormy weather is slowing the fight against the coronavirus in San Francisco.

COVID-19 test centers have fewer hours and the City College mass vaccination center is closed until Friday.

The San Francisco Department of Emergency Management fears that the expected high winds and heavy rain could endanger patients and employees.

The lines at the City College vaccination center were long all morning Tuesday as people waited anxiously to be vaccinated.

“I’m so happy my mom made it,” said Jennifer Chow. “Really, really happy moment for us.”

At the mass vaccination center that opened a few days ago, everything went smoothly. But the storm forces an undesirable pause.

“I had an appointment that was later, but then they postponed it. I was very happy to see that I could come today,” said Pat Mier. “When I saw the rain coming, I wanted to get this over with.”

A testing site on Potrero Hill is also closed until Friday, and the Embarcadero testing center has reduced its hours to close at 4 p.m. on Tuesday.

Dates are being postponed and officials said no vaccines will be lost.
