SITUATION OVERVIEW
------------------
HURRICANE LALA WILL CONTINUE TO BRING DAMAGING WINDS, HEAVY RAINFALL
LEADING TO FLASH FLOODING, AND DANGEROUSLY HIGH SURF TO PORTIONS OF
THE STATE THROUGH THE WEEKEND. IMPACTS ARE ONGOING OVER PORTIONS OF
THE BIG ISLAND OF HAWAII, SPREADING WESTWARD ACROSS MAUI COUNTY AND
OAHU THIS EVENING INTO TONIGHT, AND KAUAI LATE TONIGHT INTO SUNDAY
MORNING. LALA IS SKIRTING THE SOUTHERN END OF THE BIG ISLAND OF
HAWAII THIS EVENING AND WILL PASS JUST SOUTH OF THE REST OF THE
ISLAND CHAIN THROUGH SUNDAY. DAMAGING WINDS AND HEAVY RAINFALL ARE
EXPECTED TO SPREAD WESTWARD ACROSS THE REST OF THE STATE THROUGH THE
REMAINDER OF THE WEEKEND, WITH THE BIG ISLAND OF HAWAII LIKELY
SEEING THE GREATEST IMPACTS. DO NOT FOCUS ON THE EXACT FORECAST
TRACK OR INTENSITY OF LALA AT THIS TIME, AND BE PREPARED FOR CHANGES
IN FUTURE FORECASTS. IT IS VERY IMPORTANT TO NOTE THAT THE
MOUNTAINOUS TERRAIN OF THE ISLANDS WILL LIKELY PRODUCE LOCALIZED
AREAS OF HIGHLY ENHANCED AND DAMAGING WINDS, EVEN WELL AWAY FROM THE
TROPICAL CYCLONE CENTER.
FLOODING RAIN WILL CONTINUE FOR PORTIONS OF THE BIG ISLAND OF HAWAII
AS LALA PASSES. THE THREAT FOR FLOODING WILL INCREASE OVER MAUI
COUNTY THIS EVENING AND SPREAD TO THE REST OF THE STATE LATER
TONIGHT THROUGH SUNDAY. HEAVY RAINFALL COULD PERSIST INTO MONDAY FOR
SOME AREAS, MAINLY OVER THE WESTERN END OF THE ISLAND CHAIN. LALA IS
EXPECTED TO PRODUCE ADDITIONAL RAINFALL TOTALS OF 5 TO 10 INCHES
ACROSS THE BIG ISLAND AND MAUI COUNTY AND 4 TO 6 INCHES ACROSS THE
REMAINDER OF THE ISLAND CHAIN. LOCALLY HIGHER AMOUNTS ARE POSSIBLE.
WHILE THE HIGHEST RAINFALL AMOUNTS WILL BE FOCUSED OVER WINDWARD
AREAS AND HIGHER TERRAIN, LEEWARD AREAS WILL ALSO HAVE A SIGNIFICANT
FLOOD RISK.
THE LARGE EASTERLY SWELL GENERATED BY LALA PEAKED EARLIER TODAY.
SURF ALONG ALONG EXPOSED EAST AND SOUTHEAST SHORES WILL GRADUALLY
FADE OVER THE NEXT COUPLE OF DAYS. HOWEVER, SOME INCREASE IN SURF IS
POSSIBLE ALONG EXPOSED SOUTH-FACING SHORES AS LALA CONTINUES
WESTWARD. SIGNIFICANT BEACH EROSION AND OVERWASH ARE STILL POSSIBLE
ACROSS VULNERABLE COASTAL INFRASTRUCTURE.
POTENTIAL IMPACTS
-----------------
* WIND:
POTENTIAL IMPACTS FROM THE MAIN WIND EVENT ARE NOW UNFOLDING ACROSS
THE BIG ISLAND OF HAWAII AND MAUI. REMAIN WELL SHELTERED FROM
LIFE-THREATENING WIND HAVING ADDITIONAL EXTENSIVE IMPACTS. IF REALIZED,
THESE IMPACTS INCLUDE:
- CONSIDERABLE ROOF DAMAGE TO STURDY BUILDINGS, WITH SOME HAVING
WINDOW, DOOR, AND GARAGE DOOR FAILURES LEADING TO STRUCTURAL
DAMAGE. MOBILE HOMES SEVERELY DAMAGED, WITH SOME DESTROYED.
DAMAGE ACCENTUATED BY AIRBORNE PROJECTILES. LOCATIONS MAY BE
UNINHABITABLE FOR WEEKS.
- MANY LARGE TREES SNAPPED OR UPROOTED ALONG WITH FENCES AND
ROADWAY SIGNS BLOWN OVER.
- SOME ROADS IMPASSABLE FROM LARGE DEBRIS, AND MORE WITHIN URBAN
OR HEAVILY WOODED PLACES. SEVERAL BRIDGES, CAUSEWAYS, AND
ACCESS ROUTES IMPASSABLE.
- LARGE AREAS WITH POWER AND COMMUNICATIONS OUTAGES.
POTENTIAL IMPACTS FROM THE MAIN WIND EVENT ARE ALSO NOW UNFOLDING
ACROSS THE REST OF THE STATE. REMAIN WELL SHELTERED FROM DANGEROUS
WIND HAVING ADDITIONAL LIMITED TO SIGNIFICANT IMPACTS.
* SURGE:
POTENTIAL IMPACTS FROM THE MAIN SURGE EVENT ARE NOW UNFOLDING ACROSS
THE BIG ISLAND OF HAWAII AND MAUI. REMAIN WELL AWAY FROM LOCALLY HAZARDOUS
SURGE HAVING POSSIBLE LIMITED IMPACTS. IF REALIZED, THESE IMPACTS
INCLUDE:
- LOCALIZED INUNDATION WITH STORM SURGE FLOODING MAINLY ALONG
IMMEDIATE SHORELINES AND IN LOW-LYING SPOTS, OR IN AREAS
FARTHER INLAND NEAR WHERE HIGHER SURGE WATERS MOVE ASHORE.
- SECTIONS OF NEAR-SHORE ROADS AND PARKING LOTS BECOME OVERSPREAD
WITH SURGE WATER. DRIVING CONDITIONS DANGEROUS IN PLACES WHERE
SURGE WATER COVERS THE ROAD.
- MODERATE BEACH EROSION. HEAVY SURF ALSO BREACHING DUNES, MAINLY
IN USUALLY VULNERABLE LOCATIONS. STRONG RIP CURRENTS.
- MINOR TO LOCALLY MODERATE DAMAGE TO MARINAS, DOCKS, BOARDWALKS,
AND PIERS. A FEW SMALL CRAFT BROKEN AWAY FROM MOORINGS.
* FLOODING RAIN:
POTENTIAL IMPACTS FROM THE FLOODING RAIN ARE STILL UNFOLDING ACROSS
THE BIG ISLAND OF HAWAII AND MAUI. REMAIN WELL GUARDED AGAINST
LIFE-THREATENING FLOOD WATERS HAVING ADDITIONAL EXTENSIVE IMPACTS.
IF REALIZED, THESE IMPACTS INCLUDE:
- MAJOR RAINFALL FLOODING MAY PROMPT MANY EVACUATIONS AND RESCUES.
- RIVERS AND TRIBUTARIES MAY RAPIDLY OVERFLOW THEIR BANKS IN
MULTIPLE PLACES. SMALL STREAMS, CREEKS, CANALS, ARROYOS, AND
DITCHES MAY BECOME DANGEROUS RIVERS. IN MOUNTAIN AREAS,
DESTRUCTIVE RUNOFF MAY RUN QUICKLY DOWN VALLEYS WHILE
INCREASING SUSCEPTIBILITY TO ROCKSLIDES AND MUDSLIDES. FLOOD
CONTROL SYSTEMS AND BARRIERS MAY BECOME STRESSED.
- FLOOD WATERS CAN ENTER MANY STRUCTURES WITHIN MULTIPLE
COMMUNITIES, SOME STRUCTURES BECOMING UNINHABITABLE OR WASHED
AWAY. MANY PLACES WHERE FLOOD WATERS MAY COVER ESCAPE ROUTES.
STREETS AND PARKING LOTS BECOME RIVERS OF MOVING WATER WITH
UNDERPASSES SUBMERGED. DRIVING CONDITIONS BECOME DANGEROUS.
MANY ROAD AND BRIDGE CLOSURES WITH SOME WEAKENED OR WASHED OUT.
POTENTIAL IMPACTS FROM THE FLOODING RAIN ARE STILL UNFOLDING ACROSS
THE REST OF THE STATE. REMAIN WELL GUARDED AGAINST DANGEROUS FLOOD
WATERS HAVING POSSIBLE LIMITED TO SIGNIFICANT IMPACTS.
* TORNADOES:
POTENTIAL IMPACTS FROM TORNADOES ARE STILL UNFOLDING ACROSS THE
HAWAIIAN ISLANDS. REMAIN WELL BRACED AGAINST A TORNADO EVENT HAVING
POSSIBLE LIMITED IMPACTS. IF REALIZED, THESE IMPACTS INCLUDE:
- THE OCCURRENCE OF ISOLATED TORNADOES CAN HINDER THE EXECUTION
OF EMERGENCY PLANS DURING TROPICAL EVENTS.
- A FEW PLACES MAY EXPERIENCE TORNADO DAMAGE, ALONG WITH POWER
AND COMMUNICATIONS DISRUPTIONS.
- LOCATIONS COULD REALIZE ROOFS PEELED OFF BUILDINGS, CHIMNEYS
TOPPLED, MOBILE HOMES PUSHED OFF FOUNDATIONS OR OVERTURNED,
LARGE TREE TOPS AND BRANCHES SNAPPED OFF, SHALLOW-ROOTED TREES
KNOCKED OVER, MOVING VEHICLES BLOWN OFF ROADS, AND SMALL BOATS
PULLED FROM MOORINGS.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
FOLLOW THE ADVICE OF LOCAL OFFICIALS

VIDEOS.
QUICKLY MOVE TO THE SAFEST PLACE WITHIN YOUR SHELTER IF IT BEGINS TO
FAIL, PREFERABLY AN INTERIOR ROOM ON THE LOWEST FLOOR AS LONG AS
FLOODING IS NOT A CONCERN.
IF YOU ARE PRONE TO FLOODING OR IN AN AREA UNDER A STORM SURGE WATCH
OR WARNING, BE PREPARED FOR THE POSSIBILITY OF A QUICK AND DRAMATIC
RISE IN WATER LEVELS.
