COASTAL COUNTIES WILL SLOWLY/GRADUALLY SHIFT INLAND WITH CONVERGING
BOUNDARIES ACROSS THE INTERIOR LEADING TO ADDITIONAL DEVELOPMENT
THROUGH LATE AFTERNOON. ENHANCED COVERAGE/INTENSITY EXPECTED ACROSS

WITH LESSER COVERAGE ALONG COAST...ESPECIALLY SE PORTION...WHERE
POST SEA BREEZE STABILIZATION SHOULD BE GREATEST. SOME HEAVY
