ESTA PERSPECTIVA SOBRE LAS CONDICIONES DEL TIEMPO PELIGROSAS ES PARA
PUERTO RICO Y LAS AGUAS COSTERAS ADYACENTES DEL ATLANTICO.

.DIA UNO...HOY Y ESTA NOCHE

.TRONADAS...EXISTE UN POTENCIAL DE TRONADAS CON LLUVIAS
FUERTES Y VIENTOS EN RAFAGAS BREVES ESTA TARDE A TRAVES DE PORCIONES
DEL INTERIOR ESTE, EL INTERIOR Y OESTE DE PUERTO RICO.

.INUNDACIONES...LLUVIAS FUERTES PODRIAN RESULTAR EN INUNDACIONES
URBANAS Y DE RIACHUELO.

.CALOR...INDICE DE CALOR ENTRE 100-102 GRADOS ES POSIBLE HOY
ALREDEDOR DEL MEDIODIA SOBRE PORCIONES DEL CUADRANTE NOROESTE DE
PUERTO RICO.

.DIAS DOS HASTA SIETE...VIERNES A MIERCOLES

LA HUMEDAD AUMENTARA A TRAVES DEL AREA DE PRONOSTICO HASTA EL FIN DE
SEMANA A MEDIDA QUE UN SISTEMA FRONTAL SOBRE LAS AGUAS DEL ATLANTICO
Y UNA VAGUADA EN LA SUPERFICIE INDUCIDA SE EXTIENDA A TRAVES DEL
ESTE DEL CARIBE. ESTO AYUDARA EN EL DESARROLLO DE AGUACEROS Y
TRONADAS A TRAVES DEL AREA DE PRONOSTICO. DEBIDO A SUELOS YA
SATURADOS...ESTA ACTIVIDAD RESULTARA INUNDACIONES URBANAS Y DE
RIACHUELOS AL IGUAL QUE INCREMENTOS RAPIDOS A LO LARGO DE RIOS.
DESLIZAMIENTOS EN AREAS DE TERRENO EMPINADO A TRAVES DE PORCIONES
DEL OESTE INTERIOR DE PUERTO RICO SON POSIBLES.

SE ESPERA QUE EL RIESGO MODERADO DE CORRIENTES SUBMARINAS CONTINUE A
LO LARGO DE LAS COSTAS DEL ATLANTICO DE PUERTO RICO DURANTE LOS
PROXIMOS DIAS.
