John, once a Category 3 hurricane, diminished for a time but has since re-formed just offshore in the Pacific. The storm will make an encore visit to the same area of the Mexico coast as the first round, with torrential rainfall and dangerous flooding being the greatest threats to lives and property, AccuWeather meteorologists warn.

Soon after Hurricane John became a major hurricane, it moved inland over Mexico and quickly lost wind intensity but dumped torrential rainfall near Acapulco earlier this week.
“Because part of the old circulation from John remained intact as it drifted offshore over the Pacific and regained wind intensity, the storm retained its former name,” AccuWeather Lead Hurricane Expert Alex DaSilva said.

John will drift northeastward as a tropical storm and make landfall along the Mexico coast before the end of this week. This time, the center of the storm will track west of Acapulco instead of east of the major port city and vacation destination. The first landfall was farther to the southwest along the Mexico coast.
“Interaction with land will again cause a loss of wind intensity with John, but the storm will wring out torrential rain once again,” DaSilva said.

“Especially where the old and new rain areas overlap, the risk of flash flooding and mudslides will be greatest. However, life-threatening conditions can occur even where the first round of rain stayed away,” DaSilva added.
Some of John’s strongest winds will affect Acapulco this time around, but the feature is forecast to peak at tropical storm intensity rather than that of a major hurricane.

A storm surge of up to a few feet can occur with the greatest danger of inundation near and just to the southeast of where the center makes landfall.

It may take until the weekend before all of the downpours from John as a tropical rainstorm diminish.
