TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
200 AM EDT SAT SEP 5 2015

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

The National Hurricane Center is issuing advisories on recently
upgraded Tropical Storm Fred, located more than a thousand miles
southwest of the Azores.

A tropical wave, accompanied by a large area of cloudiness and
thunderstorms, is located a few hundred miles south of the Cape
Verde Islands. This system is gradually becoming better
organized and a tropical depression is likely to form during the
next couple of days while it moves westward at 15 to 20 mph across
the tropical Atlantic.
* Formation chance through 48 hours...high...70 percent
* Formation chance through 5 days...high...80 percent

    TROPICAL STORM FRED DISCUSSION NUMBER  26
    NWS NATIONAL HURRICANE CENTER MIAMI FL       AL062015
    500 AM AST SAT SEP 05 2015
    
    Fred continues to produce bursts of convection, although the bursts
    are smaller and farther from the center than they were 24 hours
    ago. This suggests that the ongoing 35-40 kt of westerly vertical
    shear is causing a gradual weakening.  The initial intensity remains
    35 kt based on a subjective satellite intensity estimate from TAFB,
    as well as objective AMSU and satellite consensus estimates from
    CIMSS and CIRA.  The central pressure has been lowered a little
    based on additional observations from drifting buoy 13519, which
    reported a minimum pressure of 1008.4 mb as the center of Fred
    passed to the north.
    
    The initial motion is 290/10.  Fred is approaching a large break in
    the subtropical ridge caused by a mid- to upper-level trough and
    associated surface low centered several hundred miles east of
    Bermuda.  The track guidance is in good agreement that this
    baroclinic system will move eastward for the next several days, with
    Fred recurving to the northeast between it and the subtropical
    ridge.  After recurvature, there is some spread in the forecast
    forward speed, with the new track compromising between the faster
    ECMWF/GFS models and the slower UKMET/Canadian models.  The new
    track is nudged slightly to the north of the previous track from
    36-96 hours, and then is nudged a little to the east of the previous
    track at 120 hours.
    
    The intensity forecast is low in confidence due to several possible
    scenarios.  First, although it is not explicitly forecast, Fred
    could become a remnant low at any time during the next 24 to 36
    hours due to continued shear and dry air entrainment, followed by
    regeneration to a tropical cyclone when the shear subsequently
    decreases.  Second, the dynamical models have two scenarios for Fred
    as it interacts with the above-mentioned trough and surface low
    after recurvature. One possibility, supported by the GFS and the
    ECMWF, is that a relatively weak Fred gets absorbed into the
    baroclinic low and dissipates earlier than currently forecast.
    Another possibility, supported by the UKMET and Canadian models, is
    that Fred stays farther away from the baroclinic low and intensifies
    more than is currently forecast. Given the uncertainty, the new
    intensity forecast is similar to the previous forecast in calling
    for slight weakening early in the forecast period followed by slight
    intensification after 36 hours.

TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
1100 PM PDT FRI SEP 4 2015

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

The National Hurricane Center is issuing advisories on Tropical
Storm Kevin, located a few hundred miles west of the southern tip of
the Baja California peninsula.

Showers and thunderstorms have changed little in organization since
earlier today near a low pressure area located about 550 miles
south of Manzanillo, Mexico.  However, environmental conditions are
conducive for development, and a tropical depression is likely to
form over the weekend while the low moves northwestward at 5 to 10
mph well offshore of the coast of Mexico.
* Formation chance through 48 hours...high...70 percent

    300 AM MDT SAT SEP 05 2015
    
    South-southwesterly shear around 30 kt has displaced all remaining
    deep convection northeastward over the central Baja California
    peninsula, more than 120 n mi northeast of the presumed low-level
    center.  A recent ASCAT pass sampled the western half of the
    circulation and showed no tropical storm force winds.  The initial
    intensity is set at 35 kt as a blend of the latest Dvorak numbers,
    with the assumption that tropical storm force winds might still be
    occurring within the eastern side of the circulation, which wasn't
    sampled by the scatterometer.  Strong shear will continue advecting
    the leftover convection away from the low-level circulation, and
    barring redevelopment of new convection, Kevin will likely become a
    remnant low later today.  Winds are forecast to quickly decrease,
    and the NHC intensity forecast is very close to the IVCN intensity
    consensus.  Kevin is expected to dissipate by 48 hours, as shown by
    the latest global model fields.
    
    The center has been difficult to locate, but microwave images
    suggest that it has been tugged northeastward by the convection.
    The initial motion is 010/6 kt, but now that Kevin is becoming a
    shallow cyclone, it should be steered slowly northwestward and
    then westward by 36 hours.  The latest NHC track forecast is a
    little east of the previous one, only because of the adjusted
    initial position.

Interesting Weather Facts
? CLOUD HEIGHT
The cloud height on this site is an estimate of cumulus clouds using a formula based on temperature and dew point. Actual measurements of cloud height are made with a Micropulse Lidar (MPL). This device fires a laser into the sky and measures the backscattered signal. Costs for such a device are beyond the scope of weather hobbyists.
