A storm moving into San Diego County from the south brought thunder and lightning to the South Bay early Monday.
“In the South Bay, people are hearing the loud ‘Boom’ of thunder,” said NBC 7 Meteorologist Jodi Kodesh before 7 a.m.
“This thunderstorm may even produce hail,” Kodesh said.
By noon, many communities in the East County and South Bay reported not only thunder and lightning but rain.
Most of the heavy rain was concentrated in the mountains with more than half of an inch falling on Mount Laguna. Alpine reported approximately a third of an inch.
