    Hurricane Enrique Discussion Number 14
    NWS National Hurricane Center Miami FL EP052021
    900 AM MDT Mon Jun 28 2021

    The convective structure of Enrique has eroded some this morning as
    the hurricane appears to be feeling the effects of dry air
    entrainment, both from downsloping to the northeast off the higher
    terrain of Mexico and from stable air being entrained from the
    northwest. This degradation in the northern portion of Enrique's
    inner-core structure is also seen in an 0919 UTC AMSR2 microwave
    pass. The latest subjective Dvorak intensity estimates were T4.5/77
    kt from both TAFB and SAB, and the intensity for this advisory was
    lowered to 75 kt in accordance with these estimates.

    Enrique's motion appears to be gradually turning more toward the
    left at 335/4 kt. Over the next few days, a weak low- to mid-level
    ridge is expected to keep the storm on a similar northwest heading.
    The latest track guidance is in relatively good agreement, though
    there have been notable leftward shifts in the HWRF and HMON models.
    The latest NHC forecast is a slightly farther left compared to the
    previous one, close to both the TVCE and HCCA consensus aids.

    Now that Enrique's inner core structure has become increasingly
    ragged, weakening is expected to continue via dry-air entrainment as
    the storm tracks along gradually decreasing oceanic heat content.
    The latest NHC intensity forecast is a bit faster in its weakening
    rate over the next 24-36 hours, but Enrique is still forecast to be
    a tropical storm as it approaches the Baja California peninsula.
    However, some uncertainty remains in the forecast intensity because
    Enrique is forecast to track along a sharp sea-surface temperature
    gradient, where a left shift in the track would likely result in
    faster weakening rate while a right shift in the track may allow
    Enrique to maintain its intensity longer.

    Given the latest forecast, the government of Mexico has issued a
    tropical storm watch from Cabo San Lucas to Los Barriles along
    southern part of the Baja California Peninsula.

    Key Messages:

    1. The outer rainbands of Enrique are likely to produce heavy rains
    across a portion of western Mexico during the next couple of days,
    which could likely cause life-threatening flash flooding and
    mudslides.

    2. The core of Enrique is still near but just offshore the
    southwestern coast of Mexico this morning and a Hurricane Warning is
    in effect for a portion of that area. Tropical-storm-force winds
    are expected to continue across the remainder of southwestern Mexico
    within the warning areas through today. Hurricane conditions are
    possible in the Hurricane Watch area today.

    3. Swells generated by Enrique are expected to affect the
    southwestern coast of Mexico during the next few days. These swells
    could cause life-threatening surf and rip currents.
