Puerto Rico faces another day of rain and thunderstorms on Monday, November 9, with heat from morning hours as humidity and weak winds combine, National Weather Service (NWS) meteorologist Carlos Anselmi Molina said. Little wind will drive heat over the region and, although no advisory is being issued, he urged vulnerable people to stay hydrated and out of direct sun.
"The available humidity with that excessive heat mixed with local effects will help generate showers and electrical storms, at times strong, that can cause flooding in those urban areas and in bodies of water like streams," Anselmi Molina said. Because the winds are weak, the rains could linger, potentially bringing flash flooding "in those areas already saturated by the rains of the past five days."
He said Monday’s shower and thunderstorm activity could benefit the La Plata basin and is a beneficial opportunity for the reservoir. Coastal conditions will be dangerous because of thunderstorm activity in several northern towns, along with a high risk of rip currents for that region. He urged caution and said beachgoers should visit balnearios and lower-risk places, warning that lightning from the storms could affect the coast.
