Will Simon become a hurricane?
The NHC forecasts strengthening during the next 48 hours. Its current forecast says Simon is expected to become a hurricane by late Thursday and could become a major hurricane by Saturday.
That is a forecast, not a guarantee. Storm intensity can change quickly, so the latest NHC advisory should be treated as authoritative over older projections.
What parts of Mexico face the biggest rain risk?
Current forecast reporting says Simon could produce 8 to 12 inches of rain across portions of southwestern Mexico, with isolated totals potentially reaching 15 to 25 inches in Colima and Michoacan. Heavy rainfall can create flash-flood and landslide risk, especially in mountainous terrain.
At the time of formation, the NHC had not yet posted a coastal watch in the 3:00 p.m. CST advisory shown on its main storm page, but it said watches would likely be required as the system approached Mexico. Official warning maps can change between advisories.
What does the forecast cone mean?
The NHC forecast cone shows the probable track of the storm’s center; it does not show the full size of the storm or the complete area that can receive heavy rain, wind or rough surf. Hazardous weather can occur outside the cone.
The official cone currently bends Simon generally northwestward toward the southwestern coast of Mexico before carrying the center farther northwest. The exact land interaction and intensity remain uncertain several days out.
How Simon compares with other active storms
Simon is one of multiple active tropical cyclones being monitored. In the Atlantic, Tropical Storm Isaias is strengthening in the Gulf and has hurricane and storm-surge watches in effect for portions of the northern Gulf Coast. Hurricane Rachel remains active farther west in the eastern Pacific. These are separate systems with different tracks and hazards.
