TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
800 PM EDT SAT SEP 20 2014

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

An elongated area of low pressure continues to produce disorganized
cloudiness and showers near and to the southeast of the Cape Verde
Islands.  Environmental conditions do not appear conducive for
development, and tropical cyclone formation is not likely.
However, the low is forecast to move slowly northwestward and could
bring heavy rainfall to portions of the Cape Verde Islands during
the next couple of days.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.

For the eastern North Pacific...east of 140 degrees west longitude:

The National Hurricane Center is issuing advisories on Tropical
Storm Polo, located about a hundred miles south of the southern tip
of the Baja California peninsula.

An area of disturbed weather located a couple hundred miles south of
the coast of Guatemala is producing disorganized showers and
thunderstorms. Environmental conditions are expected to become
conducive for gradual development of this system during the next
several days while it moves slowly westward or west-northwestward.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...30 percent.

  • Tropical Storm POLO Forecast Discussion Number 19
    Issued at 200 PM PDT SAT SEP 20 2014 000 WTPZ42 KNHC 202037 TCDEP2 TROPICAL STORM POLO DISCUSSION NUMBER 19 NWS NATIONAL HURRICANE CENTER MIAMI FL EP172014 200 PM PDT SAT SEP 20 2014 Polo is a sheared cyclone, and the cloud pattern consists of a tight swirl of low clouds with intermittent deep convection. The initial intensity is kept at 40 kt at this time, but given the hostile environment and the cooler waters, weakening is forecast. Polo will likely become a remnant low in about 36 hours. Polo has been moving between northwest and west-northwest since yesterday at about 5 to 7 kt. The cyclone is trapped south of an amplifying mid-level ridge over Mexico, and this pattern should force Polo to move on a west-northwest to west track for the next 2 to 3 days, and then the remnant low should meander until dissipation. The NHC forecast has not changed, and continues to be very close to the multi-model consensus. Based on the forecast track and wind radii, tropical storm force winds are anticipated to remain south of the Baja California peninsula. Since any unexpected deviation to the north of the forecast track could bring tropical storm force winds to the coast, the Government of Mexico is keeping the tropical storm watch until Polo begins to move away from Baja California Sur.
