Hurricane Lane Update #4- Heavy rains forecast

The 11:00 AM forecast track brings Hurricane further north increasing the likelihood of a direct hit. The National Weather Service has forecast sustained winds of 25-35 MPH with gusts up to 50 MPH for most of the main Hawaiian Islands. Good news is the storm that Hurricane Lane is forecast to weaken as it approaches the islands, but there is a very real danger of severe flooding from the possibly heavy rains.

Please continue to pray for the hurricane to dissipate before making landfall or to miss the Hawaiian Islands.  The other prayer needs remain the same, so please pray that the sub-tropical ridge to remain strong and push Lane south of Hawaii. Please pray for people to remain calm, heed the watches and warnings, and prepare the storm. Please pray for homes and property to be protected from damaging winds and rains.

Here are some excerpts from the latest forecast discussion from the Central Pacific Hurricane Center. Please pay special attention to the Key Messages at the Bottom.

Lane is moving a bit slower this morning and appears to have wobbled
slightly to the WNW during the last few hours, and the initial
motion for this advisory is 280/8 kt. Lane has been moving westward
to the south of a mid-level ridge during the past several days.
However, this will be changing soon, as Lane begins to round the
western periphery of this ridge and moves into an area of
relatively light steering flow. This is expected to allow the
cyclone to gain latitude as its forward speed diminishes. The
hurricane is forecast to turn gradually to the west-northwest
through tonight, then to the northwest Wednesday through Thursday,
as it moves between the mid-level ridge to the east and a developing
upper-level trough to the northwest of Hawaii. After this point, the
track and intensity forecasts remain highly uncertain, as the
majority of the reliable model guidance brings Lane very close to
the islands with potential interaction between Lane and the
mountainous terrain of the islands. This interaction combined with
increasing vertical wind shear leads to a weakened Lane being
steered to the west by the low-level trade wind flow. The new track
forecast has been nudged slightly to the north or closer to the
islands from 36 through 72 hours, into better agreement with the
multi-model consensus HCCA.

Water temperatures along the forecast track will be sufficiently
warm to support a major hurricane, and thus any significant
weakening before Lane draws closer to the Hawaiian Islands will
likely be due to increasing wind shear. In the short-term through
the next 24 hours or so, shear is expected to remain light, and
expect only slow weakening as the cyclone moves over slightly
cooler SSTs and may be impacted by eyewall replacement cycles.
At 72 hours and beyond, the forecast anticipates a sharp increase
in shear as Lane moves closer to the large upper trough to the
northwest of the main Hawaiian Islands. The new intensity
forecast is close to the previous forecast, and although it
remains on the high end of the guidance envelope, it generally
follows the trends presented by the multi-model consensus IVCN and
HCCA.

KEY MESSAGES:

1. Lane is forecast to move dangerously close to the main Hawaiian
Islands as a hurricane later this week, potentially bringing
damaging winds and life-threatening flash flooding from heavy
rainfall. As Lane is expected to be slow-moving as it nears the
islands, it will produce large and damaging surf. A Hurricane Watch
remains in effect for Hawaii and Maui counties, and additional
Tropical Storm or Hurricane Watches may be required this afternoon
or tonight.

2. It is much too early to confidently determine which, if any, of
the main Hawaiian Islands will be directly impacted by Lane. Even
if the center of Lane were to remain offshore, it is important to
remember that impacts from a hurricane can extend well away from
the center. Interests throughout Hawaii are urged to closely
monitor the progress of Lane during the next few days.
