The NOAA has recently issued an advisory for tropical storm Narda, downgrading the storm which developed in the Pacific Ocean over the weekend to a tropical depression. Narda is one of three systems currently churning either side of the US and Central America and is expected to batter Mexico’s west coast this week. The storm has the potential to cause deadly effects, with more than a foot of rain possible in places.
According to the NOAA, Tropical Depression Narda will hit Mexico tonight.
However, after making landfall, it is expected to weaken and could completely dissipate by tomorrow.
The National Hurricane Centre (NHC) in the US earlier said Narda “is expected to continue with some decrease in forward speed during the next day or so.”
The storm has since downgraded and is spinning with 35mph winds.

The advisory reads: “At 600 AM MDT (1200 UTC), the centre of Tropical Storm Narda was located near latitude 27.1 North, longitude 110.1 West.
“Narda is moving toward the northwest near 14 mph (22 km/h).
“Narda is forecast to continue moving along the northwestern coast of mainland Mexico this morning.
“Maximum sustained winds have decreased to near 35 mph (55 km/h) with higher gusts.”

The NOAA has discontinued former tropical storm warnings for Mexico, but the storm could still cause dangerous conditions with heavy rainfall.
Narda will produce the following rainfall accumulations:
– Sinaloa: one to two inches, isolated totals 10 to 15 inches.
– Chihuahua: one to three inches.
– Sonora: one to two inches.

NHC forecasters have warned flooding is possible in Sinaloa early on Tuesday, and northwest Mexico is on alert for isolated flash flooding.
The effects of Narda could also bleed into the US, as moisture spreads north.
Moisture from the system may spread into the southern US plains and prompt “enhanced” rainfall and flash floods.
Areas on Mexico’s west coast are also at risk of storm swells, which are expected to spread north and generate “life-threatening surf and rip current conditions”.
