SITUATION OVERVIEW
------------------
TROPICAL STORM LALA IS EXPECTED STRENGTHEN TO A HURRICANE AND BRING
DAMAGING WINDS, HEAVY FLOODING RAINFALL, AND DANGEROUSLY HIGH SURF TO
PORTIONS OF THE STATE THIS WEEKEND. IMPACTS ARE STARTING TO BEGIN ON
THE BIG ISLAND OF HAWAII TONIGHT, THEN WILL SPREAD INTO MAUI COUNTY
LATE TONIGHT INTO SATURDAY MORNING. OAHU AND KAUAI CAN EXPECT IMPACTS
TO BEGIN BY LATE SATURDAY AFTERNOON INTO SATURDAY EVENING. LALA IS
EXPECTED TO PASS OR MAKE LANDFALL OVER THE SOUTHERN END OF THE BIG
ISLAND OF HAWAII ON SATURDAY AND PASS JUST SOUTH OF THE REST OF THE
ISLAND CHAIN THROUGH SUNDAY. DAMAGING WINDS AND HEAVY RAINFALL IS
EXPECTED ACROSS THE ENTIRE STATE THIS 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.
DAMAGING TROPICAL STORM FORCE WINDS WILL BEGIN TONIGHT ACROSS PARTS OF
THE BIG ISLAND OF HAWAII AND MAUI COUNTY, WITH HURRICANE FORCE WINDS
POSSIBLE AS LALA MOVES NEAR OR OVER THE BIG ISLAND SATURDAY. DAMAGING
WINDS ARE EXPECTED TO SPREAD WESTWARD TO OAHU AND KAUAI LATER SATURDAY
AFTERNOON AND INTO SUNDAY. 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 BE POSSIBLE TONIGHT ON THE BIG ISLAND OF HAWAII,
BUT THE THREAT OF FLASH FLOODING WILL QUICKLY RAMP UP ON SATURDAY AS
LALA APPROACHES. THE THREAT FOR FLOODING WILL BEGIN OVER MAUI COUNTY
ON SATURDAY AND SPREAD TO THE REST OF THE STATE LATER SATURDAY AND
SUNDAY. HEAVY RAINFALL COULD PERSIST INTO MONDAY FOR SOME AREAS,
MAINLY OVER THE WESTERN END OF THE ISLAND CHAIN. LALA IS EXPECTED TO
PRODUCE RAINFALL TOTALS OF 10 TO 20 INCHES, WITH LOCALLY HIGHER
AMOUNTS POSSIBLY UP TO 25 INCHES, ACROSS WINDWARD BIG ISLAND. RAINFALL
TOTALS OF 8 TO 12 INCHES ARE POSSIBLE ON WINDWARD MAUI AND UP TO
8 INCHES OF RAINFALL COULD OCCUR ACROSS THE REMAINDER OF THE ISLAND
CHAIN. WHILE THE HIGHEST RAINFALL AMOUNTS WILL BE FOCUSED OVER
WINDWARD AREAS, LEEWARD AREAS WILL ALSO HAVE A SIGNIFICANT FLOOD RISK.
LARGE SWELLS GENERATED BY LALA WILL BUILD TONIGHT AND PRODUCE
DANGEROUS SURF ALONG EXPOSED EAST AND SOUTHEAST SHORES OF ALL ISLANDS.
VERY LARGE AND EXTREMELY ROUGH SEAS ARE EXPECTED TO RAPIDLY INCREASE
TONIGHT INTO SATURDAY ON EXPOSED SOUTHEAST AND EAST SHORES OF THE BIG
ISLAND AND MAUI, AND THEN OAHU AND KAUAI BY LATE SATURDAY. DAMAGING
SURF, SIGNIFICANT BEACH EROSION, AND OVERWASH ACROSS VULNERABLE
COASTAL INFRASTRUCTURE IS POSSIBLE.
POTENTIAL IMPACTS
-----------------
* WIND:
PREPARE FOR LIFE-THREATENING WIND HAVING POSSIBLE EXTENSIVE IMPACTS
ACROSS THE BIG ISLAND OF HAWAII. POTENTIAL IMPACTS IN THIS AREA
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.
ALSO, PREPARE FOR DANGEROUS WIND HAVING POSSIBLE LIMITED TO
SIGNIFICANT IMPACTS ACROSS THE REST OF THE STATE.
* SURGE:
PREPARE FOR LOCALLY HAZARDOUS SURGE HAVING POSSIBLE LIMITED IMPACTS
ACROSS BIG ISLAND OF HAWAII. POTENTIAL IMPACTS IN THIS AREA 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:
PREPARE FOR LIFE-THREATENING RAINFALL FLOODING HAVING POSSIBLE
EXTENSIVE IMPACTS ACROSS BIG ISLAND OF HAWAII AND MAUI COUNTY.
POTENTIAL 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.
PREPARE FOR DANGEROUS RAINFALL FLOODING HAVING POSSIBLE LIMITED TO
SIGNIFICANT IMPACTS ACROSS OAHU AND KAUAI COUNTY.
* TORNADOES:
PREPARE FOR A TORNADO EVENT HAVING POSSIBLE LIMITED IMPACTS ACROSS
THE BIG ISLAND. POTENTIAL 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
* OTHER PREPAREDNESS INFORMATION:
NOW IS THE TIME TO COMPLETE ALL PREPARATIONS TO PROTECT LIFE AND
PROPERTY IN ACCORDANCE WITH YOUR EMERGENCY PLAN. ENSURE YOU ARE IN A
SAFE LOCATION BEFORE THE ONSET OF STRONG WINDS OR POSSIBLE FLOODING.
IF YOU ARE RELOCATING TO SAFE SHELTER, LEAVE AS EARLY AS POSSIBLE.
ALLOW EXTRA TIME TO REACH YOUR DESTINATION. MANY ROADS AND BRIDGES
WILL BE CLOSED ONCE STRONG WINDS ARRIVE. CHECK THE LATEST WEATHER
FORECAST BEFORE DEPARTING AND DRIVE WITH CAUTION.
IF HEADING TO A COMMUNITY SHELTER, BECOME FAMILIAR WITH THE SHELTER
RULES BEFORE ARRIVAL, ESPECIALLY IF YOU HAVE SPECIAL NEEDS OR HAVE
PETS. TAKE ESSENTIAL ITEMS WITH YOU FROM YOUR EMERGENCY SUPPLIES KIT.
FAILURE TO ADEQUATELY SHELTER MAY RESULT IN SERIOUS INJURY OR LOSS OF
LIFE. ALWAYS HEED THE ADVICE OF LOCAL OFFICIALS AND COMPLY WITH ANY
ORDERS THAT ARE ISSUED. REMEMBER, DURING THE STORM 9 1 1 EMERGENCY
SERVICES MAY NOT BE ABLE TO IMMEDIATELY RESPOND IF CONDITIONS ARE
UNSAFE. THIS SHOULD BE A BIG FACTOR IN YOUR DECISION MAKING.
KEEP CELL PHONES WELL CHARGED. CELL PHONE CHARGERS FOR AUTOMOBILES
CAN BE HELPFUL, BUT BE AWARE OF YOUR RISK FOR DEADLY CARBON MONOXIDE
POISONING IF YOUR CAR IS LEFT IDLING IN A GARAGE OR OTHER POORLY
VENTILATED AREA.
IT IS IMPORTANT TO REMAIN CALM, INFORMED, AND FOCUSED DURING AN
EMERGENCY. BE PATIENT AND HELPFUL WITH THOSE YOU ENCOUNTER.
IF YOU ARE A VISITOR, BE SURE TO KNOW THE NAME OF THE CITY OR TOWN IN
WHICH YOU ARE STAYING AND THE NAME OF THE COUNTY OR PARISH IN WHICH
IT RESIDES. LISTEN FOR THESE LOCATIONS IN LOCAL NEWS UPDATES. PAY
ATTENTION FOR INSTRUCTIONS FROM LOCAL AUTHORITIES.
RAPIDLY RISING FLOOD WATERS ARE DEADLY. IF YOU ARE IN A FLOOD-PRONE
AREA, CONSIDER MOVING TO HIGHER GROUND. NEVER DRIVE THROUGH A FLOODED
ROADWAY. REMEMBER, TURN AROUND DON'T DROWN!
IF IN A PLACE THAT IS VULNERABLE TO HIGH WIND, SUCH AS NEAR LARGE
TREES, A MANUFACTURED HOME, UPPER FLOORS OF A HIGH-RISE BUILDING, OR
ON A BOAT, CONSIDER MOVING TO A SAFER SHELTER BEFORE THE ONSET OF
STRONG WINDS OR FLOODING.
CLOSELY MONITOR WEATHER.GOV, NOAA WEATHER RADIO OR LOCAL NEWS OUTLETS
FOR OFFICIAL STORM INFORMATION. BE READY TO ADAPT TO POSSIBLE CHANGES
TO THE FORECAST. ENSURE YOU HAVE MULTIPLE WAYS TO RECEIVE WEATHER
WARNINGS.
